Questions
How big is the STM32 Devboard PCB?
It measures 27.8 × 61.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32 Devboard use?
39 parts, built around the TLV1117-33DCY, USBLC6-2P6, PMEG3020EJ and Q13FC1350000400. 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 STM32 Devboard KiCad files?
From the tsk04/STM32-development-board repository on GitHub, at the commit this page was made from: the board is STM32 Devboard.kicad_pcb and its schematic STM32 Devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32 Devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask tsk04 before reusing the design.
