Questions
How big is the PowerBoard PCB?
It measures 100 × 65 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PowerBoard use?
144 parts, built around the CH340E, MCP25612FD-E/SL, LM7805 and NJM7812SDL1-TE1. 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 PowerBoard KiCad files?
From the mgsin30/Robocon2025-PCB repository on GitHub, at the commit this page was made from: the board is PowerBoard/PowerBoard.kicad_pcb and its schematic CANBusHub/CANBusHub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PowerBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask mgsin30 before reusing the design.
