## Description
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](https://github.com/chrismyers2000/MeshAdventurer) project by Chris Myers.
- Based on the widely available ESP32-S3-DevKit-C clone board
- LoRA modules: [EByte E22-series](https://www.cdebyte.com/products/E22-900M30S)
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.
