Questions
How big is the Board v1.1 PCB?
It measures 79.9 × 68.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Board v1.1 use?
117 parts, built around the TLV8811DBV, DRV8825PWP, 74LVC1G08Z and PCF8523T. 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 Board v1.1 KiCad files?
From the stustanet/spacelock repository on GitHub, at the commit this page was made from: the board is board_inside/board_v1.1/board.kicad_pcb and its schematic board_inside/board_v1.0/board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Board v1.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask stustanet before reusing the design.
