I envision the development kit consists out of two components;  a laser head and a main board.
This post sheds more light on the main board.
The main board can be programmed and powered via USB C. These are two "regular" USB 2 connectors. The CH224K chip is used to request 12V from the power source. The main board uses a ESP32 S3 and connects to the laser head via USB C 3.1.
This is not a regular USB C connector. In an ideal world, you could connect to the laser head with USB C using your laptop.
I am working towards this, and therefore I am starting to support USB C 3.1. I will share more details on this in the future.
The main board features three stepper drivers, to move the laser head. Angled pin headers are used to connect to the end stops and stepper motors. A micro SD card reader is present for additional storage. The ESP32 S3 already provides 32 MB storage, so this should not be needed. The black box is AK-NW-84 (100x67x22m) and can be found online.
