Questions
How big is the Cooldrv PCB?
It measures 20.2 × 14.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cooldrv use?
11 parts, built around the DRV8825PWP, WSLP0603R0500FEA and MM3Z3V3T1GX. 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 Cooldrv KiCad files?
From the kliment/cooldrv repository on GitHub, at the commit this page was made from: the board is cooldrv-kicad/cooldrv.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cooldrv design in my own project?
Its repository states no licence, so its author keeps all rights: ask kliment before reusing the design.
