Questions
How big is the MyMachine LED cap PCB?
It measures 70 × 59.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MyMachine LED cap use?
58 parts, built around the DRV8873HPWPRQ1, LM74610QDGKRQ1, ADXL345BCCZ and ST1L08SPU33R. 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 MyMachine LED cap KiCad files?
From the BrnoMarsRover/myMachine-LED-cap repository on GitHub, at the commit this page was made from: the board is pcbs/main_board/main_board.kicad_pcb and its schematic pcbs/main_board/accelerometer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MyMachine LED cap 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).
