Questions
How big is the STM32G4 PCB PCB?
It measures 35.6 × 35.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM32G4 PCB use?
82 parts, built around the STM32G431CBU6, TPS73633DBV, USBLC6-2SC6 and TS-1187A-B-A-B. 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 STM32G4 PCB KiCad files?
From the wallComputer/STM32G4_PCB_V2 repository on GitHub, at the commit this page was made from: the board is STM32G4_PCB.kicad_pcb and its schematic STM32G4_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32G4 PCB 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).
