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
LoRA modules: EByte E22-series

Key features:

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.
