Questions
How big is the Distributor PCB?
It measures 147.3 × 114.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Distributor use?
46 parts, built around the ULN2804A. 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 Distributor KiCad files?
From the mentlerd/playground repository on GitHub, at the commit this page was made from: the board is resources/flipdot/01_FGY_128x16/distributor/distributor.kicad_pcb and its schematic resources/flipdot/01_FGY_128x16/distributor/distributor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Distributor design in my own project?
Its repository states no licence, so its author keeps all rights: ask mentlerd before reusing the design.
