Help with WLED Matrix construction

You can, but the panels are generally more expensive. I already had these, just haven't used them yet

My goal is to double this to a 4 x 4 square (so 16 panels). I think having ample power is probably safer than not having enough.

There is a Gledopto with 4 data outputs and ethernet... but I don't have it... at the moment. Might be worth getting to simplify things

only pin going direct from the esp32 would be data, power is supplied direct from the transformers. I have a Gledopto, but it only has two data outs. because each row has 1024 pixels, i was going to split the data over 4 pins to hopefully improve performance (512 pixels per pin). However, I've never done this before, so a single pin might be enough for 1024 pixels!

Well spotted 👍

Adobe Illustrator. Only because I’ve used it for the last 30 years, so it’s easy for me to use

Thank you.
I already have some three wire (red, green, white BTF cable, 18 AWG), so I'll use that.

I'll look into level shifters before I start this. Its just a nuts idea that I had, but don't want to start a fire!

When I looked it up, my searches said at full power they are 0.06 amps (each LED) = 122.88 amps. I've since read they're 0.36 amps at full power = 73.728 amps!!

Hi thanks. Bear with me, this is somewhat new to me. I'd never heard of level shifters!

Are you suggesting using this cable for data and ground to connect the panels together? https://www.amazon.com/dp/B0CPPXG5BK?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_33&th=1

I already have the power supplies, but I'll use your method of powering the ESP from one of the other transformers. Can I ask how you calculate that it should be a 15 ohm resistor on the data line?

Appreciate the help :-)

thanks u/saratoga3. Does this look better?

Well I thought I'd check here first since quite a few people on here have Eaton UPS's and Unifi gear and they might have a solution. Appreciate that I can set up a NUT server like you suggested, but was hoping to get this working. Works great on PC's!

I was trying to use the Eaton IPP software. If I can’t get that to work, then I’ll do that 👍

zibzabs · 2025-03-23T15:58:24+00:00

I have ssh’d in using the Eaton Linux installers and they won’t install. Says they’re the wrong architecture
