Questions

How big is the Hallmoeba PCB?

It measures 19.1 × 19 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Hallmoeba use?

24 parts, built around the SLSS49E-3 and SK6812MINI-E. 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 Hallmoeba KiCad files?

From the gamaPhy/Hallmoeba repository on GitHub, at the commit this page was made from: the board is hallmoeba/hallmoeba.kicad_pcb and its schematic hallmoeba/hallmoeba.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Hallmoeba design in my own project?

Its repository publishes it under the CERN-OHL-P-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).
