Questions
How big is the Mainboard v02 PCB?
It measures 90.2 × 95.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mainboard v02 use?
152 parts, built around the ATSAMD51J20A-AU, EP2W+, MAX4372TEUK+T and MR25H40MDF. 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 Mainboard v02 KiCad files?
From the pycubed/hardware repository on GitHub, at the commit this page was made from: the board is mainboard-v02/mainboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mainboard v02 design in my own project?
Its repository states no licence, so its author keeps all rights: ask pycubed before reusing the design.
