Hi ! Very nice video! Incidentally if any one tries to connect similar Chinese boards with 12 Volts as their barrel socket specifies, they are sure to burn up the 5 volt SMD regulator. I have burnt three of them not realizing their design flaw. After seeing your video I replaced a regular 7805 ( non SMD ) , with pin modifications and some peeled off tracks reconnection, and it works like silk. Thanks to your video initiative.

There's something about plugging in the PSU that's worth a mention. The power supply can be plugged just as easily into one end of the breadboard or the other - but if you plug the power supply into the wrong end, just as you did, you will be plugging the positive into the blue rail and the negative into the red rail. Chips get hot and melt the breadboard! In my case, it was one op-amp of a set of 25 that I got at very low cost - so I lost a few pence. I was lucky it wasn't an Arduino Nano, or something more expensive than that!

Just so we all are on the same page... A multi meter will read the average voltage, so it can be more or/and less and it will pick the middle and display that. As you showed, it's 4.96 and 3.31 average therefore neither power output is correct. If you were testing and as you were trying to show. The only way to test a power supply is with a oscilloscope. This gives you I formation of jitter, noise, voltage deviations and such like. You would then have to put a load on there going the full range of the IC/FETs to see how it performs and if it is uniform. Higher current may cause a voltage drop, lower draw make have voltage spikes. Also if there is a power on spike. This happens a lot with devices and would be down to the IC and that schematic to see if this is a problem, or is increased or decreased with the board design. Also.... Most chips would take a input on 8v 500ma... But there are lots of different ones. If your getting hot, it may be the cause??

Comments: a) If you provide 12V to a 5V linear regulator at 0.1A, to do it's job it converts 12-5=7V @ 0.1A into heat, 0.7 watts. If you provide 7V to a 5V linear regulator at 0.1A, it converts 7-5=2V @ 0.1A into heat, 0.2 watts. Less heat = longer life. If you draw too much current, you will burn out the regulator. There is no heat sink on the regulators on this board, so you won't get the max. rated current (1A) without problems. b) According to one schematic I saw on the net for a MB-102 (don't know what the schematic is for this board), the USB connector is for power input, not output. If you try to use it as a power output, what you are doing is feeding whatever voltage is from the barrel power jack directly to the USB device. Since USB devices are expecting 5V, giving it 7V - 12V would be bad. c) The USB input jack should be a mini or micro type. Putting a USB-A connector on here goes against the USB spec. There are MB-102's on eBay that have proper mini or micro jacks. d) If you power the board using USB power, it is 5V. Supplying a 5V linear regulator with 5V does not give you 5V, it gives you something less, or maybe nothing. So only expect the 3.3V regulator to work with 5V input.

My 0.1A figure is just for a heat calculation example. I don't know what is needed for a Raspberry Pi. According to a website, somewhere between 0.5 and 0.7A is needed for an RPi 3, depending on what is connected. I'd guess you'd need to put a heat sink on the regulator to pull this kind of current. raspberrypi.stackexchange.com/questions/341/whats-the-current-draw-and-supply-voltage-tolerance

The usb is power and program. I'm pretty sure that it's not usb and power jack, but I can't see if there is a blocker to stop the cross over and if it acts as a controller for usb out. It doesn't look like this as it's is using the PR's with almost a direct connection hence the jumpers. As for power/heat. Unless the chips are identified then it's hard to tell the total power. .7C/w is fairly common. But then so are heatsinks. I've a "5a" using a surface mount, about 30% the size of what I'd expect, there is a HS, but it isn't good enough. your right the differential or I /V is the live or die of these chips. Lower is better.

Interesting video but you missed a couple things that are indeed very important.. plugging it into the wrong end of the 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 ON (assuming that it was simply a bad MB102 module and I swapped in a new one), and it immediately went to +11.34 and literally with nolonger 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...

In other video I saw in a demo that the USB port is able to light an LED, hence, that USB port is intended to supply power and not receive power. Therefore, this power supply module has only ONE power source and that power source shall come from the jack. The USB port shall propagate the power that comes from the jack towards anything connected to the USB port.

The 3 volt and 5 volt options was designed for adrino and pi accessories. For example my pi can only handle so much so prefered method if running a lot of different items on the gpio is to use transistors that run on the 3 volt to trigger relays running on 5 volts. If you are running anything with a pi or andrino i recommend using a transistor triggering a relay to switch on/off the circuit. They have a board out there i belive with relay and transistors soldered in for controlling higher loads. some are even house 110ac compatible relays.

I thought that too - his presentation is a little tedious. I did a course on microprocessor programming on KZitem some time ago. It runs for about 5 hours, and I spent a l-o-n-g time going through it and eliminating all the ums and urs.

That would be 5v as per standard USB spec.

Out of curiosity, the dc adapter you used, was the center pin + or -?
@awesomearduinoreview4133

The center pin should be positive. Most DC circuits have diodes to prevent accidental connection of the wrong polarity. However, its always best to check with a multimeter that the center pin is indeed positive.

I ended up doing something similar, I used my multimeter on that setting that beeps when you have a connection, and with one lead on the power supply center pin and then the other on the board itself where you connect to the bread board(which are labeled + & -), so once I had a connection beep, I knew the polarity of the center pin, yay :)

Can you use the USB port also as INPUT with a male to male USB cable?

No. The voltage is to high. A car battery is charged up to 13,8 V.

How many volts is coming to power supply module ?? I bought a cheap bench power supply that's got a knob on it, that has setting 3v, 4.5v, 6v, 7.5v, 9v, 12v. Not sure which one to use. Thanks for any help!
@MichaelJohnson-mb1io

These power supply are not accurate and you need to measure the output voltage with a voltmeter. Without that, try 6V or even 5V.

Also, be careful with polarity (which usually can be set on the power supply). Check the circuit on the module to see whether center pin is + or -.
