Questions
How big is the Controller board PCB?
It measures 38 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller board use?
76 parts, built around the ESP32-S3-MINI-1-N8, WS2812B and CUHS20S60,H3F. 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 Controller board KiCad files?
From the rmf-hru-wg/E-PIX_controller repository on GitHub, at the commit this page was made from: the board is controller_board/controller_board.kicad_pcb and its schematic controller_board/controller_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller board design in my own project?
Its repository states no licence, so its author keeps all rights: ask rmf-hru-wg before reusing the design.
