great vid.. here's what I just observed yesterday.. you missed a couple things that are indeed very important.. plugging it into the wrong end of a longer breadboard (as mentioned) is OK to do, but it sets up and inverted polarity on the breadboard where it's + output pins drive the ones labeled (-) on the breadboard's labeling... but if you keep that straight you're fine using it that way.. Several longer breadboards only extend this power half way down the rails too so be prepared to jumper + and - across the gap in the middle if yours are like that too. Secondly these YwRobot breadboard regulators cant take 12.0vdc, I would recommend they only be fed with 6 to 9vdc adapters.. I had 4 of them all fail very recently in exactly the same way before I realized that I'd grabbed the wrong wall-wort adapter and was feeding it 12.25 vdc ( unloaded) .. and here is precisely what each one did as it failed..
1.) under a NO load condition with this +12.25 vdc applied thru the barrel jack produced want looked like Ok voltage out across the rails and was looking good at + 5.02 vdc .. it looked fine but when switched off then connected to a actual load... 2.) and turned back ON while under LOAD its GRN LED immediately started blinking at a slow .5 second rate and the output voltage under light loading was then reading only + 0.02VDC.. NOTE: I think this is a ONE TIME ONLY Fused -Open behavior to protect the load.. But then ... 3.) disconnecting the load and turning it OFF then back ON gave a normal steady ON GRN LED BUT the actual output on the rails from this regulator was exactly +11.34 VDC and it stayed that way every time you switched it OFF and back ON with or without a load connected.. I made the mistake the 1st time this occurred of having a little MPU 5060 accelerometer module plugged IN and I did not check the vltg after it was BLINKING GREEN at it's .5 second rate.. and as I powered it back ON (assuming that it was simply a bad MB102 module and I swapped in a new one), it immediately went to +11.34 and literally with no longer a 0.02vdc out again.. this +11.34 smoked the regulator chip on the MPU 5060 when I turned it back ON.. it was sparking and billowing smoke before I could unplug it.. since switching the regulator switch OFF had no effect.
4.) after seeing it do this BINKING in a FAIL SAFE FUSED OFF to then switch over and start putting out +11.34 VDC on the rails not just once but on a total of 4 of these YwRobot MB V2 regulators .. I finally started researching the source and I am now 99% sure now that it was my 1.5 amp 12vdc wall wort that triggered all the failures of these regulators... Lesson learned.. If you ever see that GREEN LED start BLINKING as you power it ON.. do UNPLUG the load immediately and test the output voltage on the rails because after cycling the switch ON/OFF/ON a 2nd time, the +5V voltage is way too hot, it's over twice that at 11.34vdc.. DO NOT leave it connected to the load as you turn i back ON since you may be using a +12vdc or higher output transformer adapter by mistake like I was...
Thanks. A great review. Small point though. Please note that you have mounted it on the wrong side of the breadboard. The red line holes on the breadboard do not match the +ve on the power supply. The power supply should be mounted on the right side of your board and then the colour code matches.

Yes, you connect a USB cable to power up your Arduino board. But beware: Read the following link and read the comments, there are some issues most probably with some old boards. I have got one recently and it seems to work OK. ik1zyw.blogspot.it/2015/03/breadboard-power-supply-module.html
you can connect for example an ardunio with the black power jack with a 9v battery and with the usb jack to the breadboardpowerboard. it works, so it is right. but it works the other way around aswell.
Ive use it for my home weatherstation. Pretty cheap and you get what you paid for. Its not very efficient and if you draw around 200mA at the time, the voltage converter chip gets increddible hot. Therefore i mounted a heatsink.
Nice vid! I believe it is supposed to be fed by 5-9V DC... Ideally 9V. If you go high as 12V, the 5V side ends up providing 8V (!). Depending on the brand of the protoboard, this device should be installed at the lower rows, or upper rows, to match the polarity color-coding (colored stripes) of the breadboard.
hi, great video! Unfortunately this module doesn't fit my breadboard... I have a matsuhama breadboard and now i have to construct an adapter pcb to fit it on.Anyway the quality of the module is good.
Mine came with the DC plug short circuited! Fortunately saw it before pluging anything in! Pay attention to it when you buy those little Chinese stuff!
HELLO!!! Are you trying to burn up stuff? put the board on the bottom of the breadboard... the red is positive and you have it hooked to blue which is negative and you have blue hooked to positive...people associate red with positive. put the board on the other side...then red will be positive and blue will be negative...wonder how many people smoked something by following this?
Why do you need to use one of these if you're working with an Arduino? Would it just be solely to stop having to run wires from the Arduino Ground/5V to the breadboard?
I have one of these. I feed it with 12V. On the 3.3V setting it outputs 3.3V. On the 5V setting it outputs 8V! So be careful with this one and measure the output voltage. I took a chance and connected an ESP-8266 to get power from the USB port and it worked, but I suspect it's not a good idea to use it for powering.
You can use the usb port as a power input as long as you connect only one power supply at a time. use usb or the traditional dc port but never both of them. :) added up voltage can damaged regulators.
Thank God! I thought I was the only one with this problem! I completely agree with you! I have the same problem with this piece of C**p! I want to center my servos and decided to plugin the servo tester that takes 4.8 to 6.0 V as input. I'm glad that I decided to check the voltages because I was using this board without looking at the documentation . Therefore, I wanted to make sure that I set the jumpers correctly and I was getting the proper voltage out! I am constantly getting 8 V output at the 5 V pins! What a pain! And I don't even know what that push button switch does! Does anyone know what it does?
I bought 5 of them. One blew out the electrolytic cap upon first application of 12V. Only one of the other four had spec output of 3.3v & 5 v. Measure BEFORE using.
WTF? This thing was a power supply? I thought it added USB port to my bread board. I was trying to build a solar power phone charger. Now I know why it was draining the battery.
I thought you glossed over the set of parallel jumper pins towards the middle of the module. I was asking a store consultant what they were for and he placed the jumper plug across 2 of the pins and instantly cooked the module causing it to spark and smoke badly. I have not been able to find any information so far about this set of pins and what they are for and how they are used or configured. The power module I bought came with no documentation or instructions.
@ Ian Barton. Very simple two +5v and two +3.3v pin out as well as a straight line of four ground (GND) pins as inidcated. Very handy if you connect some jumper cables to power a device off the breadboard. Naturally you would never short voltage directly to ground as your store consultant did.
You can use the usb port as a power input as long as you connect only one power supply at a time. use usb or the traditional dc port but never both of them. :) added up voltage can damaged regulators.
You could. The switch on the board is a 6 pin latching pin... generic thing. Looking at the bottom of the board.. it'd be super easy just to desolder the switch right off the board and you can send your own signal in at that point.
Thanks for the video. My search lead to this page after my crappy board was outputting 8 V at the 5 V pins. Not sure if the board is bad. Do you know what that push button switch is for? thanks!
Hey! My one camed without a jumpers, but it's not a problem. When I plug a battery it works fine, but after connecting it to power supply it doesn't work at all. The polarity right, and i checked few power supply (9v, 1,3 A, standard guitar unit). The LED is off all the time and it's not giving any voltage. You guys have any advice?
To fix the jumper problem, you can use a female to female dupont jumper wire. As for it not working after connecting it to a power supply.. that sounds strange. If the LED is off, even after pressing the switch.. that's telling me that you may have shorted the board and burned it out. Without having the unit in front of me, there's not much I can help you with. Sorry.
Yeah, I know this trick, but right now I'm setting the lab, and i suffer from lack of jumpers, wires etc. About the power supply. After plugging the jack and the LED didn't respond, I plugged it back to 9v battery and it worked fine. I'm assuming it's not broken. Maybe the power supply didn't have enough current to drive the circuit, I need to measure current consumption, or maybe, my battery-to-jack converter have differnt polarity, there is a lot of research ahead of me.
I'd suggest only using this during your prototype/testing phase. When it comes to powerbanks and dealing with LiPO batteries, there's a ton of other things to look out for such as over-charge protection and drainage.
