## Description
The MeshPoE-S3 is a universal PCB designed for use in LoRA mesh networks such as **Reticulum**, **Meshtastic**, and **MeshCore**.
The MeshPoE-S3 is a universal mesh node designed for use in LoRA mesh networks such as **Reticulum**, **Meshtastic**, and **MeshCore**.
It is mostly designed for stationary deployment and PoE power.
- Based on the [WaveShare ESP32-S3 ETH Development Board](https://www.waveshare.com/esp32-s3-eth.htm)
- LoRA modules: [EByte E22-series](https://www.cdebyte.com/products/E22-900M30S)
Key features:
- **Compact form factor** suitable for embedded outdoor mesh nodes
- **Power-over-Ethernet (PoE)** support for convenient outdoor deployment
- **Ethernet connectivity** for mesh networking
This repository contains the KiCad project files, PCB schematics, board images, and Gerbers for fabrication.
- **Compact form factor** suitable for outdoor mesh nodes
- **Power-over-Ethernet (PoE)** support for convenient outdoor or roof deployment
- **Ethernet connectivity** for reliable wired networking
- **GPIO headers** for easy customization and expandability
- Optional **DS3231MZ+ RTC** for timekeeping
- Optional **I2C** environment sensor support (BME280, BME680, etc)
This repository contains the KiCad project files, PCB schematics, board images, Gerbers for fabrication.
You are welcome to alter the design to fit your requirements.
