Build it from the project documentation linked in Sources. Components and assembly are required.

Notes

The v3 design has footprints for E22-900M22S and E22-900M30S; the Meshtastic DR-DEV target maps the M22S radio and is marked inactive. Board assembly and the selected external antenna are builder-supplied. Designed by SudoMesh contributors. It does not establish support for the M30S footprint option.
