Questions
How big is the ModuleDriver PCB?
It measures 51.4 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ModuleDriver use?
43 parts, built around the ULN2803A, 74HCT2G04GV, MC7805BDTG and B5819W. 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 ModuleDriver KiCad files?
From the rtitmuss/splitflap repository on GitHub, at the commit this page was made from: the board is pcb/moduleDriver/moduleDriver.kicad_pcb and its schematic pcb/moduleDriver/moduleDriver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ModuleDriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask rtitmuss before reusing the design.
