Questions
How big is the Helmholtz driver PCB?
It measures 114.3 × 48.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Helmholtz driver use?
31 parts, built around the DRV8870DDA. 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 Helmholtz driver KiCad files?
From the UBCOrbit/helmholtz_driver repository on GitHub, at the commit this page was made from: the board is project.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Helmholtz driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask UBCOrbit before reusing the design.
