Questions
How big is the GearControl PCB?
It measures 70.3 × 64 mm and has 4 copper layers, 1.6 mm thick.
What parts does the GearControl use?
58 parts, built around the STM32F405RGT6, KF50BDT-TR, MP2359DJ-LF-Z and AO3401A. 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 GearControl KiCad files?
From the patwitt/PGRacingElectronics repository on GitHub, at the commit this page was made from: the board is GearControl/PCB/GearControl_v2/GearControl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the GearControl design in my own project?
Its repository states no licence, so its author keeps all rights: ask patwitt before reusing the design.
