Questions
How big is the Sense trinket PCB?
It measures 20.3 × 53.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Sense trinket use?
43 parts, built around the PCF85063AT/A. 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 Sense trinket KiCad files?
From the UCSD-SEELab/light-approx repository on GitHub, at the commit this page was made from: the board is sense-trinket/hw/design/sense-trinket/sense-trinket.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sense trinket design in my own project?
Its repository states no licence, so its author keeps all rights: ask UCSD-SEELab before reusing the design.
