Questions
How big is the Motordrive PCB?
It measures 160 × 111.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Motordrive use?
37 parts, built around the 74HC595, ULN2803 and LM2903. 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 Motordrive KiCad files?
From the mentarus/vend repository on GitHub, at the commit this page was made from: the board is motordrive.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motordrive design in my own project?
Its repository states no licence, so its author keeps all rights: ask mentarus before reusing the design.
