So!

Over the past few days, I've been finalizing the rev. 1 PCB. For now it's going quite well!
The current revision will feature USB connection and auto-reset/auto-program, battery charging & protection as well as voltage regulation, a pin for touch-input, a WS2812 LED for status output, a vibration motor connection as well as a IR input and output.

Pretty neat if that all fits onto a 23x38mm board, too!

The schematics are available on the GitHub repository as of now, and you can see how the render looks in the uploaded picture.

In a few days I'll be ordering the components and PCB off of LCSC & JLCPCB. During the delivery period I'll then focus on the code, but the whole project might come to a pause ... We'll see.
