Description

Unit PoESP32 is an ESP32 Ethernet controller integrated with PoE (Power Over Ethernet) functionality. It adopts the ESP32 built-in MAC + IP101G physical layer transceiver solution. The module comes preloaded with ESP-AT firmware, supporting various protocol stack control commands such as TCP, MQTT, and HTTP. Through serial communication, simple AT commands can be used to achieve server connection, data communication, and remote control functions. With PoE power supply, it not only saves unnecessary power cables but also provides a certain load capacity for your devices. The module reserves secondary development interfaces, and with the rich examples and protocol stack support in the ESP32 development platform, it can quickly achieve customized functions according to your usage scenarios.
