M5Stack ESP32 Ethernet Unit with PoE
The M5Stack PoESP32 Unit is an ESP32 Ethernet Unit that supports PoE (Power Over Ethernet). This module adopts an ESP32 as a built-in MAC and IP101G as a physical layer transceiver.
The unit has default firmware with ESP-AT and supports TCP, MQTT and HTTP protocols. It can connect to a server with simple AT commands through a serial port, achieving data transmission and remote control functions. This module simplifies wiring and saves labour cost with PoE power supply, and reserves the alibility for secondary development to meet your requirements.
