Questions
How big is the StmBoard PCB?
It measures 106.1 × 53 mm and has 4 copper layers, 1.6 mm thick.
What parts does the StmBoard use?
46 parts, built around the LIS3DH and MIC5504-3.3YM5. 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 StmBoard KiCad files?
From the Bcarpenter5/nait_board_dev repository on GitHub, at the commit this page was made from: the board is Kicad_Stuff/StmBoard/StmBoard.kicad_pcb and its schematic Kicad_Stuff/StmBoard/StmBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StmBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Bcarpenter5 before reusing the design.
