Questions

How big is the HallSwitch PCB?

It measures 19.1 × 18.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the HallSwitch use?

15 parts, built around the PMEG3020EP,115-JSM. 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 HallSwitch KiCad files?

From the frc971/electrical repository on GitHub, at the commit this page was made from: the board is circuit-boards/hall-switch-v2/HallSwitch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the HallSwitch design in my own project?

Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
