Questions
How big is the Central control board PCB?
It measures 80 × 107 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Central control board use?
99 parts, built around the STM32F446RET6, TMC5130A-TA and SKHHLQA010. 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 Central control board KiCad files?
From the EverydayDynamics/bjr repository on GitHub, at the commit this page was made from: the board is pcbs/central_control_board/central_control_board.kicad_pcb and its schematic pcbs/capacitive_plate_pcb/capacitive_plate_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Central control board design in my own project?
Its repository states no licence, so its author keeps all rights: ask EverydayDynamics before reusing the design.
