Questions
How big is the SplitFlap PCB?
It measures 40.1 × 89 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SplitFlap use?
16 parts, built around the A4988 and L7805. 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 SplitFlap KiCad files?
From the Dongathan-Jong/SplitFlap repository on GitHub, at the commit this page was made from: the board is PCB/SplitFlap.kicad_pcb and its schematic PCB/SplitFlap.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SplitFlap design in my own project?
Its repository states no licence, so its author keeps all rights: ask Dongathan-Jong before reusing the design.
