Questions
How big is the Mechaduino planzero PCB?
It measures 42.2 × 42.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mechaduino planzero use?
28 parts, built around the ATTINY24-20MU, A4954ELPTR-T and AS5047D. 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 Mechaduino planzero KiCad files?
From the plan-zero/zyraxes-rover repository on GitHub, at the commit this page was made from: the board is hw/Mechaduino-multi/Mechaduino-planzero.kicad_pcb and its schematic hw/Mechaduino-multi/Mechaduino-planzero.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mechaduino planzero design in my own project?
Its repository states no licence, so its author keeps all rights: ask plan-zero before reusing the design.
