SYSMATT-MATRIX-CARRIER

An all-pcb combined ESB32 based WS2812B matrix carrier and diffuser.

... It's a sandwich.

If you end up building these, please tag me on social media... @SYSMATT on X/Twitter - TY!

These cheap pre-made WS2812B flexible matrix boards are plentiful and availible on Amazon/Aliexpress/etc.

They look great through a 1mm FR4 PCB diffuser.

In this repo is the carrier board I created to control them with the common 30pin or 38pin ESP32 WROOM modules.

It supports WLED easily, and even has suport for audio reactive WLED using the common 6-pin INMP441 digital microphone modules.

The boards are assembled in a sandwich, The main electronics PCB with the ESP module, Mic module, A SN74AHCT125N used as a voltage translator, and an assortment of connector options for input/output.

The boards can be assembled "smart" (With an ESP) ... or "dumb"... where it will be chained from a smart board.

Four ESP outputs are voltage level translated in total to allow you to create large matrix displays.

There is also a fuse. Because house fires are no joke.

Designed using through hole because I have a pile of parts (Im a parts hoarder) ... And the are super easy for most people.

I will add more here when I have time. There are videos on the PHOTOS-VIDEOS directory. Also on youtube:
