Questions
How big is the Maslab PCB?
It measures 99.1 × 99.1 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Maslab use?
324 parts, built around the DRV8837DSG, 74HC595, 74HC165D and AMS1117-3.3. 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 Maslab KiCad files?
From the maslab-5/maslab repository on GitHub, at the commit this page was made from: the board is pcb/maslab.kicad_pcb and its schematic pcb/maslab.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Maslab design in my own project?
Its repository states no licence, so its author keeps all rights: ask maslab-5 before reusing the design.
