Questions
How big is the Stm32devboard PCB?
It measures 55.1 × 25 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stm32devboard use?
41 parts, built around the CC2500RGP, CH340E, SPX3819M5-L-3-3 and USBLC6-2SC6. 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 Stm32devboard KiCad files?
From the iivqum/cc2500pcb repository on GitHub, at the commit this page was made from: the board is hardware/stm32devboard.kicad_pcb and its schematic hardware/pcbdesignlab/pcbdesignlab.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask iivqum before reusing the design.
