Questions
How big is the Cistern PCB?
It measures 55.5 × 79.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cistern use?
16 parts, built around the ULN2003A and BD244C. 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 Cistern KiCad files?
From the patridu/Cistern-Hardware repository on GitHub, at the commit this page was made from: the board is Cistern.kicad_pcb and its schematic Cistern.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cistern design in my own project?
Its repository states no licence, so its author keeps all rights: ask patridu before reusing the design.
