Questions
How big is the Wristle PCB?
It measures 37 × 37 mm and has 4 copper layers, 0.8 mm thick.
What parts does the Wristle use?
50 parts, built around the DRV2605LDGS and 10051922-1010ELF. 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 Wristle KiCad files?
From the lerouxb/wristle-pcb repository on GitHub, at the commit this page was made from: the board is wristle.kicad_pcb and its schematic wristle.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wristle design in my own project?
Its repository states no licence, so its author keeps all rights: ask lerouxb before reusing the design.
