16x16 RGB Matrix

I have made quite a few projects with these cheap AliExpress panels, but something was always missing: an included microcontroller (preferably an ESP32), so I decided to make it myself.

I also included a sound sensor, but I couldn't find one on LCSC that's also compatible with WLED, so I picked an INMP441 module.

I would like to use this matrix display for a word clock project, but it's also quite a cool display to run WLED on, especially as a sound-reactive display. After quite a lot of soldering (256 individual LEDs) and fixing some solder connections, I got this beautiful display working xD
