Questions
What parts does the Prot2 use?
28 parts, built around the MPU-6050, TPS54302 and AO3400A. 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 Prot2 KiCad files?
From the serega3453/STM32_Init repository on GitHub, at the commit this page was made from: the board is schematic/rev2/rev2/prot2.kicad_pcb and its schematic schematic/Simplified/Init_PPO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prot2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask serega3453 before reusing the design.
