Hi a complete novice here. During covid i took up electronics as a hobby i have made a few simple light chasers. Coming upto valentins day i decided to make a scrolling text matrix 8x32 using ws2810b 5v led strip that didnt go well as soon as i added power it just started to smoke. I have seen pre made 8x32 matrix boards i was going to connect 2 of these and add extra power at pre made wires. I have a 5v 30w power supply and using esp32 and wled as programme. Do you think i will have problems with this??. I will be using 20awg cable. Would like to make this as its her 60th birthday in march and would be nice to have scrolling txt. Thanks for reading
Thanks ALDIY i will order parts. Thank you so much.
This is an 8x32 matrix that I built to use as my Tune To sign for my Christmas light show. All 3 injections on the matrix are tied together to provide power balancing and the beginning (18ga xConnect) and end (18ga xConnect) connections are fused. It worked fine. I can’t remember if I ever set it to full brightness as these panels get VERY bright. I doubt you would need to run a panel at anything over 50% brightness. I think I had mine set to like 15 or 20% at night an it still seemed brighter than the other items in my show.
Looks good , and yeah from my own testing those ws2812b eco ( most are like that ) will be with good brightness on less then 50% and use less power .
Believe it or not i have 32x16 of the same type made of two 16x16 only on a 12V 2A CCTV psu stepped down to 5v for both esp and panels without any injections and most of the time it is too much bright for me . It is running like that for almost two years and i used it for all the demos in discord if you even seen that .
Might be i do not like bright colors as cameras do not go well with that ( i have problem with that ) but in general i see some of the guys over thinking the power for matrix might be because they are used to strips or i am a batman
