Questions
How big is the Pipra PCB?
It measures 116.8 × 89.1 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Pipra use?
50 parts, built around the DRV2605LDGS, 74HC595 and AO3401A. 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 Pipra KiCad files?
From the ssbb/mini-pipra repository on GitHub, at the commit this page was made from: the board is pcb/pipra.kicad_pcb and its schematic pcb/pipra.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pipra design in my own project?
Its repository states no licence, so its author keeps all rights: ask ssbb before reusing the design.
