Questions
How big is the Controller PCB?
It measures 35 × 21.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Controller use?
64 parts, built around the ATSAMD21E18A-MUT, TPS629210DRLR-ET, MM5Z20VT1G and MM5Z3V6T1G. 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 KiCad files?
From the c4deszes/bike-front-light repository on GitHub, at the commit this page was made from: the board is hw/design/controller_al8891/controller.kicad_pcb and its schematic hw/design/connector-pcb/connector-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask c4deszes before reusing the design.
