Questions
How big is the Dev Pro PCB?
It measures 40 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dev Pro use?
61 parts, built around the STM32G473RET6, CP2102N-A01-GQFN24, IRF7205TRPBF and SP0503BAHTG. 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 Dev Pro KiCad files?
From the embeddedalpha/PCB-Design repository on GitHub, at the commit this page was made from: the board is STM32G473RET6 Development Board/Dev_Pro.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dev Pro design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
