Questions
How big is the SensorBoard PCB?
It measures 50.8 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SensorBoard use?
39 parts, built around the TCS34725FN, ATMEGA32U4, MIC5219-3.3YM5 and BSS138DW-7-F-ES. 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 SensorBoard KiCad files?
From the TeamMeanMachine/Electronics repository on GitHub, at the commit this page was made from: the board is 2020/Color Sensor/SensorBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SensorBoard design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
