Questions
How big is the ControlBoard PCB?
It measures 98 × 58 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ControlBoard use?
94 parts, built around the SN74AHCT1G125DBV, TPS629210DRL, CM1293A-04SO(ES) and STM32H562VGT6. 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 ControlBoard KiCad files?
From the melair/ktane repository on GitHub, at the commit this page was made from: the board is PCB/ControlBoard/ControlBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ControlBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask melair before reusing the design.
