Questions
How big is the Motor controller PCB?
It measures 98 × 98 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Motor controller use?
183 parts, built around the STM32G474VEH6, BSC110N06NS3GATMA1, FRC0402F1801TS and NRMR104F3435B2F. 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 Motor controller KiCad files?
From the Mee42/cube repository on GitHub, at the commit this page was made from: the board is motor_controller/motor_controller.kicad_pcb and its schematic motor_controller/motor_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motor controller design in my own project?
Its repository publishes it under the MPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
