Mesh

The Mesh module's schematic and board, KDMSH001 revision 1.0, viewable here and downloadable as KiCad sources.

What it is

The Mesh module carries the LoRa2021 radio with its two SMA ports, the ME31GR02 GNSS receiver with its chip antenna and backup supercapacitor, and the 20-pin board-to-board connector for the interposer. Four copper layers with a controlled-impedance RF stackup. The module's page, modules/mesh, says what it does and which GPIO is which; this page is the schematic.

Revision 1.0, released 2026-09-14, drawn in KiCad 10. Symbols, footprints and 3D models come from Kode's shared hardware library.

Files

The schematic sources, as published here. Open the .kicad_pro in KiCad 10 with the sheets beside it. The cover sheet's embedded fonts were removed from these copies and the project's text variables written in; the design is unchanged. The board layout is not published.
