I want to power 1-2 16x16 RGB LED panels and control them using a 3.3v Adafruit Feather. I want to use a 5v / 5amp wall plug. In early experiments on a homemade PCB, I connected the V+ from the 5V supply into the 3V and V- into the GND pin of the Feather. It worked fine, surprisingly. [LIGHT-PAN…

[image] timothyAllan: would something like the LM1086 be right for the job? You can use any low-dropout voltage regulator with 3v3 output voltage. As far I see, the lm1086 also suitable. [image] timothyAllan: I presume I should separate the power input to the board from the power to the…

OK, great! ... Thanks for the advice on the power separation...

So, this is a new schematic with the LM1086:

Do you think this would work?
