Questions
How big is the Mc2 PCB?
It measures 120 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mc2 use?
68 parts, built around the ATXMEGA32A4U-AU, BD6221F-E2, TLP280 and SS24. 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 Mc2 KiCad files?
From the rzoli/robot-control repository on GitHub, at the commit this page was made from: the board is motor_controller_2/mc2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mc2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask rzoli before reusing the design.
