Questions
How big is the Driver board PCB?
It measures 38.5 × 39.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Driver board use?
58 parts, built around the ESP32-C6-MINI-1U-H4, AS5047D, DS210W and WS2812B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Driver board KiCad files?
From the slimcdk/wisweep repository on GitHub, at the commit this page was made from: the board is electronics/driver-board.kicad_pcb and its schematic electronics/driver-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Driver board design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
