Ive used both, arduino is so much more versatile both because of its cheap price and easy usage. Raspberry pi sucks at doing anything that a PC should.

Amazing Arduino Course here🎉 czcams.com/users/shortssjKd5LXU4lg?si=85gzVLFvpR3QH_8c

idk why these chips do not support wifi while they do support many protocols in 2.4Ghz anyway. Makes no sense.

why not nanoVNA ? This device seems really slow and has low bandwidth

Beautifully explained sir 👏 👌 ❤️

Hi Robert, do you have a video teaching how to choose the profile for the IC? Because I have tools like siwave, but I have doubts how to select the desired impedance for the IC and also how to know the output impedance characteristics of a buck converter for example.

Can somebody explain me the equation how he get impedance from insertion loss? Im a little bit confused. Btw great video

Great work 🔥🔥

For port isolatio or noise floor you shoul terminate both ports withh 500 ohms termination. When you calibrate you shoul not connect you standards (open, short , load thru adapter), they should be connected direcly to thend of the cable to avoid any phase diffrence.

Great video! When Adinath didn't completely agree with your simplifications, he would go silent, which was also instructive! 😀

Great video! Didn't get it: what's the difference between shorted trace and blob of solder?

Very good presentation, but can I ask? Isn't it bad your S-Parameters were outside the smith chart for your passive resistor? Seems concerning since we then used those S-paramtesr to calculate Zdut

please make a video about pcb's with pictures

Correctly done. Great!

I'm sure - great again!=)

I'll stick with my atmega*8 for most projects. Current consumption easily tuned down to micro amps when needed.

Wow this is really stunning. It's crazy to me how we can pay a small amount of money to have our own custom PCBs created in this huge process that involves so many delicate steps. Thank you for the great video and explanation of the whole process.

So nice thanks sir

Towards the end, a test was run with all the options selected. Looks like there are only one measurement for each timing parameter. Will that sufficient?

Quick question, for the user LED you have the cathode connected to the ESP GPIO and the anode connected to +3v3. Doesn't the output from the esp32 produce +3v3 making both sides of the LED receive +3v3?

this tutorial was great, i really enjoyed it!

And then there’s teensy

Now i always prefer to work with stm32 instead of arduinos cuz i mastered it ( i mastered working with atmega328 too) i also work with raspberry pi pico & esp32.. but simple things need simple solutions so sometimes i use arduino nanos & pro minis for simple tasks

Can you do a tutorial on SFP footprints for SMT and THT that come with a cage? I'm unsure of the ebst approach since some cages have LED indicator chutes but you cant overlap components if you exclude the LED pads from the footprint, and if you do include the LED pads then you are missing 2-20 LEDs depending on the type of cage. My specific use case is a SFP Connector MOLEX_76047-5003

Greetings Robert. Great video, I just want to ask you about a particular topic. Is there a way to link multiple pads to a single pin (like in altium designer)? I can't find information related to that topic.

The peak current distribution inthe reference plane (i.e. J(0) just underneath the trace) should be same for all h's (i.e. J0/PI) acording to the formula given in slide 4, unless J0 is also a function of d. What am i missing here?

My go-to is the pi pico

Esp32 is cheaper than an arduino

Amazing video, thank you!!! I am a beginner and i find this video really helpful!

Thank you, Robert. Very helpful and insightful. I like your open mind on this problematic board. I think each supplier has their own strengths, which can greatly support your different projects, if you use them well.

Arduino: 90% programming/debugging 10% productivity

@1:55 I can smell this image 😆

subscribed, and liked the vid, thanks.

or another option is to use typical 4 stand telephone wires and use them to make jumpers that lay flat on the board. You have a wire stripper anyways

.. that's three separate motors, yaw tilt and roll? Whatcha makin mr engineer dude

Ima go with the ASUS prime b650 Wi-Fi plus

stupid to compare hardware and mostly software framework that also work on ESP32, say esp32 + Arduino better than avr + Arduino

What he meant is 95% of the time you want an esp32 based platform

Don’t forget TI C2000 series boards. Best at everything!

Esp32 with esphome. WiFi and Bluetooth on most devkit

Raspberry Pi Pico (RP2040 MCU) - very good MCU! Killer feature is PIO blocks and Interpolators

anyone implemented MPC on microcontrollers before?

sometimes issue comes in st board and we dont know reasons why this happened.

What an Amazing Video! Kudos to everyone who has put in the effort to put this together. As Robert rightly pointed out that most of the folks including me getting into the field of electronics believe that return current is the current that leaves the negative terminal and goes into ground, but now i have a much better understanding! Thankyou

Really interesting stuff, thank you! Now how about when designing a LDMOS 440Mhz driver amp for let's say 5W output. Now every inductance counts, also for those decoupling capacitors. When using a single capacitor it will have a resonance frequency offering no decoupling at all near that frequency, often in the neigbourhood of a few 100 Mhz, that's why I still use those 3 values, 1nF, 10nF and 100nF on the powerrails., each having different resonant frequencies. I still think this is better solution than a single decoupling capacitor... What is your opinion about this? I hope to see an answer but looking at the other comments I guess I will not get one...

Saw the video while programming PIC16f628 😅

One phrase to describe an esp32, "A cpu on a stick".
