The MeshAdventurer-S3 is a universal mesh radio designed for use in LoRA mesh networks such as Reticulum, Meshtastic, and MeshCore. It is inspired by MeshAdventurer project by Chris Myers.

Based on the widely available ESP32-S3-DevKit-C clone board
LoRA modules: EByte E22-series

Key features:

**Fully featured for all popular mesh networks
**Wide input voltage support for convenient mobile usage
**GPIO headers for easy customization and expandability
**Optional DS3231 RTC for timekeeping
**Optional I2C environment sensor support (BME280, BME680, etc)
**Optional ATGM336H GNSS receiver support
**Optional EC11 Rotary Encoder support

This repository contains the KiCad project files, PCB schematics, board images, Gerbers for fabrication. A case design is also available as a Fusion 360 project and a set of STL files for 3D printing. You are welcome to alter the design to fit your requirements.
