From the project

Open-source USB/BLE desktop programming controller with RGB status integration

Open Micro is an original open-source 96 × 96 mm desktop programming controller. Its industrial stack uses a CNC 6061-T6 aluminum bottom, a continuous neutral-frosted polycarbonate light-carrying wall, and a matte-black control PCB as the exposed structural top. A lower sister PCB carries the MCU, power, USB, RF, and eight hidden wall emitters.

This repository describes an unqualified two-board first article. Automated source, protocol, host, firmware, fabrication, CAD, collision, and artifact checks are design evidence only. No fabricated unit has completed docs/qualification.md; do not…
