I’ve been trying to make my LED board work for the past 10 hours, but no matter what I try nothing happens. For context I have: Adafruit RGB Matrix Bonnet for Raspberry Pi RGB LED Matrix Panel I’ve tried disabling the 1-wire and enabling it, as well as followed the advice on this https://learn.a…

I’ve got exactly the same problem! Tried on a Raspi zero 2W & also a v4 in case it was my soldered header. No luck with either. Please let me know if you find anything!!!

Did you see the other person’s comments that it worked with a 32 bit OS? Might try that myself. Will let you know if I get anywhere.

no i didn’t see that comment! could you link me to it? we think it’s actually a power supply issue and tested with a smaller screen which worked - but i’ll try your recommendation today as well and let you know!

Could well be; the product page quotes “<=20w” for the 64x32 panel, and that’s before you leave any for the Pi itself.

we’re using a 5V 3A power supply, which is 15w. do you think i should go for a 5V 4A power supply? thanks :)

Well I mean in theory it should be enough unless you had everything bright white anyway, but not all PSUs are equal, I guess?

i think it’s actually an issue with the LED board itself… because everything is working fine on a 32x16 board. i’ll try with a higher voltage but maybe i’ll reorder a board.

[image] Adafruit RGB Matrix Bonnet for Raspberry Pi Projects I thought I was going to get yet more problems driving 64 x 64 LED Matrices. The Adafruit Matrix Portal M4 is an absolute disaster zone. I have spent months trying to tweak Adafruit Tutorials and failed miserably…

Just a FYI post. I have two 64x32 panels setup as 64 x 64, it was the only way to get the pixel spacing I wanted. I’m using a Pimoroni Interstate 75 (RP2040 Micro Python). My current (no pun intended) supply is a 5V 4A switching power supply. Smooth sailing once I got my code working. ;) Don’t chea…

I’m using a 10A 5v supply for a 32 x 64 display. Nothing at all is showing though! Not even one LED :-( @alphanumeric - what version of Raspberry Pi & what OS are you using please? It should all just work out of the box and I’ve done tons of Raspberry Pi projects in the past without issue. Just t…
