# 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.

## Schematic

Zoom with the wheel, drag to pan, and switch sheets from the toolbar.

## 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.
