Questions
How big is the Helmholtz Controller PCB?
It measures 180 × 125 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Helmholtz Controller use?
13 parts. 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 Controller KiCad files?
From the cmu-argus-2/Helmholtz_Controller repository on GitHub, at the commit this page was made from: the board is Helmholtz_Controller.kicad_pcb and its schematic Helmholtz_Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Helmholtz Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask cmu-argus-2 before reusing the design.
