I did see another Blog (Richard Mudhar I believe) where the 5V AMS chip was desoldered and replaced with a 7805 to provide a "robust" first stage of voltage drop down
Mine failed too: 5V regulator short circuited, burned atmega328 and some led in the process.
My one broke, a faulty 5V regulator. I gave up with these and bought a bench power supply. I have the smaller one which worked great but I needed more power for LED strip testing.
Best up and coming channel for this topic!
Thanks for watching!
I've got the first board and encountered the same problem where the 5v jumper isn't working on either side, is there anything that can be done, or is it worth attempting to repair? I'd been using a 5v usb, decided to try a 12v barrel jack plug with an arduino uni relay circuit and noticed the voltage read was 14 so figured something was off which is why I'm googling and stumbled upon this video, the 3.3 seems to be working fine after everything, the relay and 2 led resistors seem fine as well
I did some more testing, measured the leads on the 5.5 regulator to confirm that's the problem, the output voltage on the middle pin is the same as the input, I also measured the voltage from my acdc 12v output power adaptor, which was measuring 14 volts, sounding like certain adaptors might operate at a higher voltage and then output the advertised 12 volts when plugged into the actual device they were designed for, it's known as a no load voltage or something, would still appreciate any insights others have as I'm new to this whole world
My employeer had some leftover parts from an old arduino/RPi project we did and my boss let me keep them. It included two versions of the black power supply you showed. Going to test them and hopefully nothing dies on me haha.
Great video man, your channel is awesome
So the first module he showed technically had 3 power outputs right? I’m wondering bc I need a power supply regulation Arduino board with 3 outputs for several projects I have. Each module I’m using needs 5 volts to operate but I don’t want a ground loop and I need something to regulate it all. And this would be great for that, I’d be supplying the board (shown in the beginning of the video) with a BMS board that has a 12,000 mAh lithium polymer battery, and even tho the BMS board outputs 3.3v I’d be adding a buck boost converter to boost the output voltage to 6v and into the power management supply board. It seems like it should work but I’m not entirely sure if it will. But I still need 3 separate power outputs outputting 5v each. Do you think this would work?
can it use 12v dc 2a power supply?
That first module blows its regulators really quickly. No protection or limiting if you make a mistake, or even briefly brush the wires against it each other.😢
How can I get 9v output from the module?
Buy a 9v battery. Obvious solution was obvious.
Not so obvious though, is that you can probably get 8.3 volts if you series the 5V on the one side with the 3.3V on the other...😉
If you put 5v in, how the F you got over 9V. There is not step up chips on that little board.
Great for sensors 3.3V
It wasn't 5v in. it was 12volts which is within spec...was explained later in the video
