This is an incomplete and unverified work in progress. Do not order boards or rely on this design without independently reviewing the schematic, layout, footprints, mechanical fit, and electrical connections.
The project was initially created from a Smiðr export, then received substantial additional modifications. It is no longer an unmodified Smiðr export.
