Questions
How big is the Stm32pcb PCB?
It measures 61.1 × 40.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32pcb use?
47 parts, built around the CH340C, AMS1117-3.3 and TS-1088-AR02016. 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 Stm32pcb KiCad files?
From the elight2/stm32pcb repository on GitHub, at the commit this page was made from: the board is stm32pcb.kicad_pcb and its schematic stm32pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask elight2 before reusing the design.
