Questions
How big is the Mirobot PCB?
It measures 110 × 31.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mirobot use?
55 parts, built around the CH340G, PCF8591T/2, 74HC595 and LD1117S33CTR-HXY. 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 Mirobot KiCad files?
From the mirobot/mirobot-pcb repository on GitHub, at the commit this page was made from: the board is Mirobot.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mirobot design in my own project?
Its repository states no licence, so its author keeps all rights: ask mirobot before reusing the design.
