This is a very basic laser show driver for the ESP32.
The schematic for the board is here - https://oshwlab.com/chris_9044/laser-show-driver-breadboard

You can either build this on breadboard or get a custom PCB made by JLCPCB.
You'll need a device with PSRAM (or you'll need to remove some of the ILDA files) as currently the files are all loaded into memory before use.
This project uses PlatformIO and the ESP IDF.
