The system is controlled by an ESP32 running ESP-IDF and FreeRTOS.
The switches are handled by I2C port expanders. The LED strips are controlled by WS2812 chips.

I'm particularly proud of this because this PCB was a "first" in multiple ways
* It was my first PCB made with '''LibrePCB'''[https://librepcb.org/] (that actually works). If you want do create PCBs with an open source tool and found Eagle much more usable than KiCad, you should check it out.
* It's my first 4-layer PCB. 2 Layers would probably have been sufficient if I spent more time on optimizing the design. But I wanted to try out making a 4-layer PCB anyway.
* It's the first time I soldered TSSOP packages. They are a PITA if you are as motorically incompetent as I am.
