Please do a project with one of those! :-D
Yes try to do two builds, one with the cheap components and a copy but in quality components, then let the two "run to done" and se if the more price is worth it. :-)
Micro dragons ....Dave do a project for us
Dave it's all micro please do a micro timer circuit for us
Using rf
140mz to 1gz
Buy them Dave... it looks like a great item.
Definitely make a great video too.
I bet my ass he already has
Dave! You should buy them all and make follow up videos on how to. We young players will appreciate soo much!
laughs, dam that steve and his 1337 filtering skillz.
Please buy these and try to program !
The "nop" is required when dealing with RMW (read-modify-write) ports, if you set a bit on an IO port, and then set another bit, what the hardware does for the second write is read back the port value, modify it, and write it back. The problem is if the IO line you previously set is capacitivly loaded the read back on the second write instruction might still see a "0", and the write back will clear that bit, nullifying the first write. This is a common problem in earlier PIC microcontrollers that didn't have a shadow buffer for the port drivers.
Very good. Brings back memories of fun and games with the PIC16Fxx family, etc.
I'd love to see you doing a video about that. But not only to prove, that 3ct chips work (we already know that) but more how usable they are.
Tinkerers will have a Problem with them being one time programmable, so I would look if there are flash-variants for Development. (I don't want to solder in a new mcu, when I change my code)
Also these 3ct jobbies are a bit limited, maybe try a bigger one from the same family or one that is compatible with the same programmer you can go back to smaller/cheaper chips easily, when you realize that you don't need as much pins, but being one pin short can be a pain in the backside, if there isn't a bigger chip.
In conclusion I would say that I'm much more interested in the tool-chain that in shaving off half a cent of the price.
And If you are getting somewhere usable, consider to split it in two (or more) videos: 1. your journey what you found and how and 2. a how-to that others can follow learning from your experience in the field
Thanks for the great work you are doing.
TOM
Those would be great videos indeed! *crosses fingers*
For development there are DIP versions which don't cost much more.
In most hobby projects it won't really matter if the main-”C is 3c or 3$, but i can imagine to have a box of these to replace logic gates, or outsource small jobs like battery management etc...
If I remember correctly, they do make sockets for SMD parts and such.
Yes, you can get a spring loaded SO-8 socket, but you probably wouldn't be developing directly on the OTP chips. There's usually an in-circuit emulator (ICE) or a multi-time programmable (MTP) chip you'd develop on, then switch to OTP chips for mass production. I think I saw both MTP and ICE in the video.
Back when I was developing on Microchip PIC controllers, they had UV erasable versions you could use for development. Bad news when I managed to kill all of them one day though (It was a small shop and we didn't have many). Was glad to move to flash versions.
Let's make some cheap ass projects with the tiniest budget possible
Hackaday should make a new contest where you have a super tiny budget and you have to use only these cheap chinese parts for everything in your circuit.
I like that idea.
Shit for EVERYBODY! yay
I wanna see an Apollo flight computer running on a bunch of these, in parallel!
*your budget: 1$*
Get the programmer!
Arduino
If Dave sends the manufacturer an email and they have any sense whatsoever they will send him a few programmers and a bunch of chips for him to use and to give away. The Western/English market exposure to real hardware designers and EE's on here is priceless.
Upcycle E; yeah, esp since I could not find any for sale anywhere. One embedded board blew up with this chip too, lots of chatter.
@@UpcycleElectronics will they care? They are looking for long term contacts in very high.volumes probably
The programmer is 1cent... in a thousand quantity... lol
I've read that some of these ultra cheap companies might take a small loss on their "cheap chips" with the presumption that they will also sell some of they more expensive chip once they've hooked you.
The 6 thumbs down are from Mouser, DigiKey, Texas Instruments, Microchip, NXP, and Atmel :)
47 as of when I got to the video.
ARM, Qualcomm, and several others have joined in since my initial post.
It has 81 down now, perhaps due to the long winded intro to drag the length out to almost a half hr. I'm leaving after about 4 min with no info on chip.
I thumbed it down the video is pointless and extremely condescendant. He spends 10 minutes being amused by discovering there are companies around the world he never heard of. And because after 16 minutes, I still haven't learned anything about the microcontroller this is supposed to be about. And instead at 16:28 we get him giggling like a schoolgirl and wasting time pointing out a typo on Padauk's web site, which was absolutely uncalled for and that's when I just gave up. First time I come to this channel, and also the last time.
Your interest is infectious! When you are in a PCB factory going into the ins and outs gets me smiling âș
I challenge you to make a LED blinky with this 3 cent micro!
@@KK-pq5cf No idea how to program a microcontroller like this in assembly
The LED will be more expensive
Toward's the end of the video, they had the development window up, and the sample code was in C, not assembly. Though, I would like to see a sample in assembly, just to get a feel of its architecture. Maybe an 8051 variant, since those cross different manufactures. But being Chinese, it could be their own home grown architecture.
Blinky lights are toooo...oo simple ! If its got 14 I/O lines, start with an LED clock. 4 digit x 7 segments, using Charliplexing, that needs 28 LED segments. 6 lines charliplexed can do 30 segments. If it does end up being an 8051 variant, then Charliplexing can not be used.
learn!
michael moorrees: ' But being Chinese, it could be their own home grown architecture.' -- home grown? Wanna bet it's not 'home designed IP' ?
Challenge: Make an 8-pin dip version behave like a 555!
That could be incredibly annoying.... have the code do something odd at random.
But 555 is an analog part, how are you supposed to make one with a digital microcontroller?
You basically just have comparators and a 0-1 output. You cannot get closer to digital tbh
My concern would be 1024 steps not being enough
1024 steps is no problem if you have 3 PWM channels, but I guess this chip is so cheap, the expensive part is the resistor ladder.
It shouldn't need a PWM output, the 555 is effectively binary out anyway. The rest is just 2 comparators and a transistor to charge the capacitor and another then discharge it.
Do it Dave! Watching your design/engineer processes is really enlightening.
I don't have a clue what these chips do, or how to use them, but I just bought 10,000 because they are such a deal.
It'll make a fancy necklace.
Along with a lot package of 20,000 googly eyes to glue to them?
It IS the Halloween season...LOL...
You can dump them in a dish and dip ice cream cones in it.
Throw them as confetti at a nerd wedding.
turn it into chain mail shirt made of chips, electrically connected and it cab be a heated shirt.
Oh please do a video on this. It'd be great if you could show the process of programming these (even if it's just a screen recording of you doing so).
This MCU with embedded fonts in mask rom is awesome! A lot of characters, sizes, including Unicode. You can't even do that on your standard Arduino.
what does a font ic do?
It has normal micro, but beyond RAM and EEPROM, is has embedded mask ROM (non programable) with thousends of font glyphs in various sizes. You can use them to drive display with text for example. Many graphical displays do not have fonts, only pixels based drawing, and you need to use your EEPROM to store your fonts. Sure you can usually do fine with 100 characters (which will probably use 1kB of EEPROM), but if you want to support also more than just English language, diactricts, symbols, or Asian languages, it comes very handy, otherwise you might need to use 50kB of ROM just for font glyphs, and that could be half of your flash memory, or sometimes even all of it. I.e. I often need various symbols, like Omega, degree symbol, arrows, polish diactrics, like Ä ÄÄĆșĆŒĂłĆĆ, ÄÄÄĆ»ĆčĂĆĆ, german ones, Ă€Ă¶ĂŒ, plus some French, and Scandinavian ones or Cyrillic script.
For example I have a small LCD screen connected to small micro, and I use it as a status for computer, but also messages from internet or my mail input, as a "news" source, and notifications. These messages sometimes do have non English characters in them, and just English letters are not enough. If I would turn it into a product that is for global market, I would have really a bad time making it work well.
I vote yes on more videos with these cheap micro's and their toolchains! Excellent find. Adds a lot of new product possibilities! ALRIGHT DAVE!!!
These look like great fun. I would absolutely watch a whole series of videos playing with these.
I can't wait to see the development of a programmed chip start to finish, that would be an awesome bit of internet learning for us...
Do it! I want to see how difficult it is to develop for such a chip.
Go for it!! Looks like a great exercise in learning a very interesting, special-purpose micro. If it actually ends up being viable it could really be a benefit to the whole community, knowing about the ins and outs of such a unique product.
i have used some dirt cheap micros before but generally from ST and very little code modification required, it always a fun challenge to find the micro that has JUST enough to run what you need at the lowest cost and with a toolchain you have
also pro-tip, middle mouse button over the link opens it in a new tab
Would love a video on developing something with one of these. I'm thinking an electronic business card would be a perfect use for this. I might do that.
If you're left with enough flash "empty", you can "reprogram" them if you use assembler!
Insert some "jump if" that can be converted to "jump if not" with blank address for the jump (or similar) before every piece of code.
When you need the "bugfix", you convert the "jump if" to "jump if not" and use the blank line to insert an address for fixed piece of code that you put at the end of program (with new jump and everything). This way you can bugfix and insert new code as long as you have flash left!:)
Dave this was a FANTASTIC video, please cover more of these obscure asian micros and any other interesting ICs you find! No one else is talking about this stuff. If you could make a build video with one that would be fascinating as well!
Would love to see one of these micros in action. Thanks for the info Dave. Great stuff.
Tip: You can open a new tab by holding ctrl on your keyboard and clicking a link. Or you can just click on the link with the middle mouse button. No need to open up context menu. Nice overview by the way.
I do that deliberately to trigger people
Fuck YES!!!
I would LOVE a video on using these!
Yes! Please get some of these and do a project with them. Would love to see that!
Definitely give it a try Dave, everyone is interested to see how it goes!
LOL , there's a C compiler+IDE for them crazy... reminds me of the PIC12
I can't wait to write the TCP/IP stack with the vendor-supplied C compiler to make all my very secure IoT products out of these definitely-not-backdoored devices from obscure Chinese manufacturers selling for a price that seems almost too good to be true!
@@bitrexgm let's not get overly paranoid here... Unlike the allwinners cpus with a bunch of built in peripherals This 3 cent part has a whopping 64 byte of ram (much like the 12F family I mentioned) you shouldn't be worried about backdoors on your unrealistic tcp/ip stack you should be worried about Silicon bugs, documentation and long term availability if you are considering doing anything remotely commercial with these ...
@@bitrexgm whilst your concern may be well founded for some Chinese parts, this is a Taiwanese company. Taiwan is very much a different country.
@@benpye6854 Taiwanese semiconductor firms often subcontract fabrication to mainland China as well. But yes it seems unlikely that this particular product is much of a threat for honest manufacturers who aren't baddies themselves. but might be surprised what kind of code can be run utilizing 64 bytes of RAM and e.g. hidden inside an Ethernet port housing as in relation to recent news. not enough resources to do anything IP related? eeeh I wouldn't be so sure about that.
Has anyone here played Shenzhen IO and noticed the striking similarity in purpose?
One of my favorite fucking games ever!
I would love to see the workflow. Go for it, Dave!
Impressive response time from Mike's tweet to releasing a video. Well done Dave!
Would be nice to reverse engineer the programmer so that anybody can cheaply make one
This was my first thought. My second thought was to make it self-hosting (i.e. create a programmer for these chips using one of these chips). Bootstrapping it would be part of the fun!
That would be interesting to me too. It would be a great opportunity to explain the variety of universal programmers and contrast them to basic bootloaders that are used with various USB to serial converters. I would love to know the abstract top level info covering most programmers/microcontrollers and how they have evolved from the parallel/pc serial "pony" programmers, to the mysterious HAL/PAL/GAL's, through to things like the AVR Dragon, PickKitĂ, USBblaster, K150, TL866, Segger JLink, to the serial ICP bootloaders with the FTDI, Bus Pirate, prolific Chinese CH340G, USBasp, etc.
The main things I'm really unsure about comes down to exactly what a programmer does differently than a converter and bootloader. Where does one even start when building a programmer from scratch? Why do most cloned programmers (STlinkv2/USBBlaster/JLink) seem to use a STM32F103 (or hacked 'F101 with the sketchy USB features of a lower quality wafer/die)? Is it just a matter of establishing a higher voltage on a pin or does it come down to super complicated software protocols? Also 8bit vs 32bit ARM programmers/techniques. What's the best and cheapest option for the freeple?
does anybody see the irony of reverse engineering a Chinese product? ⊠oh how the table turns...
Robyn That's how the FLOSS driver for Allwinner VPU and device tree are made.
yeah :-D
Many architectures have instructions that require NOPs before or after them, especially branches.
often used to get around silicon bugs too where timing or caches (if used) just didn't align
Hell yeah! I'm more than ready to watch a video about hands-on experience with these micros! Dave, please do the flashing the LED =)
Great topic for a video! Thanks Dave!
A video showing what's involved in using these cheap MCU's and how they perform, what the reliability looks like etc would be very interesting
Iâve bought a lot of components from that site. They are very fast at shipping and I typically get the shipments in 2-3 days to Canada (via DHL)
Yes some of it is subpar quality but most is just fine. Iâve saved a bundle compared to Digi-Key orders.
It would be so cool to get 100 of these for ridiculously cheap and always have them on hand just in case you need one. I'd love to see you do a vid on using them!
I was expecting click-bait but, now I can't wait for part 2!
i developed a motion sensing passage light controller using one of these asian chips and must say they work great for the price and if you contact the company they will help you over skype no matter what issue. i really want you to buy one of these micro controller and develop a product with it. I have been buying from LCSC for branded parts and they are a lot cheaper for branded stuff as well considering the place where I live digikey etc charge like $70 for shipping whereas LCSC can send you over registered mail for a lot less. Recently started buying from arrow for free shpping but LCSC at times is cheaper for samsung, rubycon etc capacitors and other branded company connectors etc
I just made ~200$ order from them, i hope this will be game changer since DigiKey, Mouser... and some other companies simply ignore countries like Bosnia and they have default shipping cost of 120EUR even for a few parts of 10-20$. Also, the cost of same package to Croatia, Slovenia or Austria can be optimizes to ~15-20EUR and those are basically same region countries. I tried to reach them and suggest them to optimize that but so far nothing...
Local dealers charge about 3-5 (stupid 4017 decade counter costs 1-1.5 EURO here!!!) times and sometimes even more for anything and there is also no quantity discounts.. So i HAVE to find good online store if i want to do anything.
The shipping cost is the best part of the site.
Have you tried arrow.com? Seems like they offer free DHL delivery to Bosnia. I've checked recently with a single RPI 3B+ for $34.49 and in order summery it shows 'free shipping' & 'no tax' for address in Bosnia)
That's the point why these mcus etc. are really interesting. Dropping the price. Especially interesting for developing countries!
Have you tried Farnell UK? It is 5⏠to Slovenia, and they have extreme fast delivery, the record was 19 hours from order to doorbell!
@@tapravdec Will check...
Please do buy some of these (or maybe a slightly more expensive but even more versatile IC). And they seem surprisingly professional, compared to other similar companies. You might want to contact them - maybe we'll learn something interesting! Like how they can produce these parts at these costs.
I remember when people scoffed at the 2$ ESP8266 chips, and that they must be rubbish - but now they are everywhere.
A whole new world of opportunities with such cheap parts. Definitely worthy of designing and building projects Dave with these parts. Also font chips; that's new to me too :D
Dave get the cheapest, the tiniest and the most limited in processing and memory and make a switch mode power supply, with a high PWM resolution, fully tuned PID feedback control etc. :)
Have a look at stc they seem to be in a lot of the Chinese gadgets today. They arenât 3 cents but for around 30-40 cents for small quantities you can get a pretty respectable set of ram/flash/eep and periphs, and best of all they all have built in rom uart boot loader for which there is open source python programming tool (stcgal). 8051 arch so compiles with open source sdcc, and shameless plug... now has platformio support for ide like experience.
Jens Jensen Have you got any decent resources on the STC you can link? Thanks!
Yes please create a project with one of these - really would love to see that!
Not wimpy instructions. Powerful.
Lol @ "Synwit". I think I'm going to start calling my mates synwits
This time it was in fact Chinese :D Mandarin is just the spoken language
That's what's confusing about Chinese: all these languages using the same writing and it works??
@@coffee115 It's more like extreme accents rather than languages.
@@coffee115 yeah, and we also have different "versions" of writing, like simplified or traditional types. Just because it is sort of a pictographic character system, you can even read very ancient writing on a stone just by learning the writing system of the newest simplified version.
@@coffee115 plus, you may also be able to "understand" part of Japanese just because they also use some Kanji ("Chinese") characters in their writing system.
Yeah, from what I've heard, over 50% of written Chinese or Japanese can be understood by someone who knows the other language.
Yes, definitely do a project with one of these chips!
It would absolutely be interesting to see how well a project turns out. Go ahead :D
Yes Dave, it's 0Hz when it's off ;-)
Oswyn Faux It's 0Hz when stopped in a hardware debugger. It also means that an external clock could be run really show (like 0.1Hz in a timer application) without destabilizing the chip. This is a characteristic of CPUs with static circuitry, like the venerable Z80A. Depending on their design they may also be able to stop the internal oscillator when waiting for an external interrupt while preserving the full internal state.
@@johnfrancisdoe1563 It was a joke John
Oswyn Faux No, static performance is special. So no take, there. Gotta have a turn; maybe the power use goes down in this incubator controller when clocked under 330bpm?
@@Cineenvenordquist Again, it was a joke.
nice stuff!...maybe you should make a project with a bunch of em all talking to each other..for no reason other than they are cheap!
That's both hilarious and interesting!
A project with these would be great, but using the font chip is a MUST!
I have a Chinese speaking (well literate) friend or two for making contact with suppliers and establishing good relations. They love it when people use a translator to ask questions. According to a mate, the effort often scores bonus goodies (loot!) like samples and even quite expensive kit like development boards.
Do it! It'll be a quite nice change from all the Arduino/ESP32 hype.
Could we find one that would be more usable for hobbyists. Something better than the atmega328 at those cheap prices could be interesting.
Especially now that those are out of stock.
Agreed, but let's not detract from the incredible price of this little guy!!
I also would love to see you do a separate video showing development using these chips!
A series of videos on this little guy would be awesome!
100 chips...cart...buy.....make video. This is not a comment... these are your instructions.
Make a beowulf cluster supercomputer out of them! I'd totally watch that (and the soldering live streams).
You can probably fit million cores in a small room. Wouldn't even cost that much.
6502 project?
Doing a project with them would be great! Many thanks for your videos.
Yes, please do a project with them. Looking great
they offer 0.3$ 16-bit dac and 0.5$ 16-bit adc! is that for real!?!?!?!?
the price probably is :P
Yes it is cheap. Certainly not $0.03 cheap but still quite cheap for a 16 bit DAC/ADC if it is any good
Is this real life o is this just fantasy?
@Lassi Kinnunen MP3 players dont have DC accurate 16 bit ADCs and DACs in them. Audio DACs are always cheaper.
+Lassi Kinnunen
Are they real 16 bit DACs in those super cheap MP3 modules or are they 9-10 bit DACs or faking it with PWM?
lol damn there were 900 left between the PMS150 and PMS150C, i went out for 30 mins and when i got back they were sold out..
550 in stock right now. They are probably just whipping their involuntary labor harder to produce chips faster.
Gotta shave cents off those prices. Thanks China!
i order some a hour ago... they had 20 in stock...
Gone again
I've been using lcsc for a few months, no complaints.
Yes ! Please develop some cheap fun gadget with this. Maybe even use 2 of them in tandem to improve the capabilities.
Amazing how cheap they can make components.
Yep. Slavery FTW.
A micro with I2C going to an LCD with I2C adaptor that can display time from an RTC and Temperature and humidity from a suitable sensor on the I2C bus and make an Alarm clock.
Getting a Font PROM for fancier fonts on the LCD would be cool.
Simples ! đđđđđđđđđâ
Looks like fun. Definitely worth doing some projects with it.
Definitely use these MicroControllers in a project!
I've come across an ABOV chip in a curbed microwave. After looking into them I'm really interested if I can figure out a real freeware toolchain without Keil. ABOV does 8051 derivatives. IIRC the MC96F6432 is the good one. Particularly it has all the usual serial interfaces, 32k flash, but most importantly, it runs on 5v and has a 12b ADC.
sdcc is getting better. I looked at it a while ago. I'm not sure if it's "there" yet. But it's free and runs on Linux & FreeBSD.
@@markg735
Yeah. I installed SDCC already, but I also picked up a few old Atmel 8051's too in order to get slightly more familiar with a better documented 8051...and a few C8051F310's from silicon labs for good measure. Exploring 8051's and a newer PIC16F1719/(XC8) I got a book for recently are on my to do list soon.
I am buying 100 for $3 and gluing them on the wall as decoration. No programmer needed...
Imagine a Beowulf Cluster of those things.
=))
yea I am, my vic20 had more cpu power and used less power.
You re not going to cover a lot of wall with 100 of these...
A fellow slashdotter I see
A video series on this chip will be awesome!!
Hmm, definitely interested to see what you'd do with these. Definitely go for it! đ
This is awesome. This kinda stuff is what makes electronics fun as a hobby - we can afford (in a sense) to screw around and play with "neat" things - even if only to find out whether they suck or not. Please, please do a small project with this, I think it'd be pretty cool. Why don't you DIY a PS/2 keyboard or something simple like that? Simple and to the point, and somewhat applicable to the real world. Nothing overly complex, but a fun exercise. And should be possible with some of these low end parts.
It's written in simplified Chinese. You can't write Mandarin, it's a spoken dialect.
Also, people who correct you on that... well, they are wrong. Mandarin is a Chinese dialect, so it is perfectly fine to say that someone speaking Mandarin is speaking Chinese.
That's kinda like saying Catalan is Spanish because it's spoken by people in Spain and uses the same letters as Spanish...
Mandarin is Chinese because it's a Chinese dialect, not because it is spoken in China.
Catalan is a different language from Spanish despite being spoken in Spain.
Different dialects don't only use the same alphabet - it's really the same when written down. Granted, some regions use simplified and some use traditional characters, so that is not entirely true and there are some minor differences in word usage, but overall it is the same. Even if it sounds nothing alike when spoken.
Chinese has many (often mutually incomprehensible) dialects. They are still the same language.
I'm not making this up, you can look it up for yourself.
@@Yotanido thats the thing though. other so-called dialects of chinese are more different than the romance languages are from each other. those dialects probably should be considered different langues, to be honest
It's actually more complicated than that. We've recently had issues with our localization into Traditional Chinese due to the a difference in a translation between Cantonese/Mandarin in Hong Kong/Taiwan, even though both write in Trad. Chinese.
Yndostrui correct
Yes, yes I think you should do a project with one of these. I've been looking at all my kids toys wondering how they can get the electronics so cheap and as usual CZcams has provided me with the answer.
I guess the 0 minimum clock frequency indicates the CPU is fully static. I.e. the CPU doesn't lose state if the clock is stopped and then just carries on again when the clock is restated. That can be incredibly useful and it also means the CPU can be run safely at low KHz to save power.
Mandarin is not a written language, it's a spoken language. The written language is referred to as being either Simplified or Traditional Chinese. So you're correct to call it Chinese, and should ignore any idiots telling you it's supposed to be called Mandarin because they don't know what they're talking about.
Do you think that putting those lucky eights in a row of four neutralizes the luck?
@@speffex I've wondered the same thing myself over the couple of decades since I chose the name. My knowledge of Cantonese numerology is not exactly what it should be. ;)
Combined assembly and C is quite normal. It is supported by GCC and other compilers. Saves time setting up complex data structures and function calls for example. One C command may generate 80 lines of assembly. Having said that it can also be used to optimse code produced by the C compiler as some can produce very verbose code. Arduino IDE also allows this. It was used extensively for optimising performance in old games without going over to full assembly/machine code.
arduino ide use avr-gcc under the hood, you can even write c++11 with it
Great video. Looking forward to the follow-up project...
This video was quite entertaining Dave. Would love for a more in depth review of them using the programmer and then ultimately finding a good use for the chip.
Are these chips compatible with american electrons or should I order chinese electrons?
No. They are not comaptible with american elections!! Read the news.
Probably would also not work with angry pixies from canuckistan
Don't forget the asian dielectric caps, won't decouple otherwise
If it explodes when you put the exact rated voltage on the pins, you're probably just holding it wrong.
they aren't compatible with imperial electrons, only metric ones ;)
Huh. This company sells a 8 megabyte QSPI SRAM. Biggest I could ever find is 512k. Time to install Doom on my NUCLEO-L432KC. Humm, might have enough power to run quake. I go
Could be fake, they just loop a 1MB 8 times, like they do it with fake sdcards. xD jk
I like LCSC, you can combine part orders with PCBs and get DHL shipping for very little more.
On the major brands, often they might be cheaper because LCSC's low volume each price will start at nearer the reel price.
Thanks Dave, extra video would be great...would love to know how reliable they are as well. Cool find !
Do something with it Dave
Yes please, would love to see them in action and by the way these are Arabic letters 11:43 and the font is awful
Yes! it would be interesting to see how easy it will be to use it.
Love it! Would be great to see to see how to use this chip, it could actually be super useful! Even shipping is cheaper than Digikey.
Ye, finally do some projects. You never did solder all those kits you got together. Just do any project
Common! YOU from all people "comment beg"? You know we want it... yes you do!
Love the EEVblog; Dave is the man, keep on going strong!
P.S. Yes, would love to see a project using these penny ic's.
I love LCSC. I use it for all my PCBA designs at work and at home. JLCPCB and ALLPCB make it very easy to source and assemble components from LCSC. I build most of my projects that I want assembled, or mostly assembled using strictly LCSC components when possible
Love to see a video of you doing a farting gnome project with the 3 cent micro. Programmer and all.
lol
Microchip will buy out the Company now....
That's funny and sad (because it's true) at the same time.
Yes, I'd like to see you getting one of these programmers and a few IC's. That and see what you can get them to do.
Can you test if these can be powered with mains?
