Questions
How big is the Devboard PCB?
It measures 23 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Devboard use?
24 parts, built around the STM32F411CEU6, AP2120N-3.3TRG1, USBLC6-2SC6Y and B3SN-3012P. 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 Devboard KiCad files?
From the zPirroZ3007/devboard repository on GitHub, at the commit this page was made from: the board is devboard.kicad_pcb and its schematic devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask zPirroZ3007 before reusing the design.
