Questions
How big is the Sensors PCB?
It measures 73 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Sensors use?
117 parts, built around the MCP2562-E/MFVAO, ADS1115IDGS, MMC5983MA and PCA9685PW. 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 Sensors KiCad files?
From the heeplr/pilotpi repository on GitHub, at the commit this page was made from: the board is sensors/sensors.kicad_pcb and its schematic power/_buzzer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensors 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).
