Questions
How big is the Minirobot PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Minirobot use?
68 parts, built around the STM32F411RET6, RN4020-V/RM and TCS34727FN. 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 Minirobot KiCad files?
From the joeferner/minirobot repository on GitHub, at the commit this page was made from: the board is pcb/minirobot.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minirobot design in my own project?
Its repository states no licence, so its author keeps all rights: ask joeferner before reusing the design.
