PoESP32 Unit is an Ethernet module that integrates the ESP32 microcontroller and supports Power over Ethernet (PoE) functionality. It combines the capabilities of the ESP32, a versatile microcontroller with built-in Wi-Fi and Bluetooth, with the IP101G physical layer transceiver.

PoESP32 Unit comes with default firmware using the ESP-AT command set. This firmware enables support for TCP, MQTT, and HTTP protocols, allowing for easy communication and data transmission over the Ethernet connection. By using simple AT commands through the serial port, the module can connect to a server and achieve remote control and data transmission functions.

One of the key features of PoESP32 Unit is its support for Power over Ethernet. This means that it can receive power through the Ethernet cable, eliminating the need for a separate power supply. This simplifies wiring and reduces labor costs, as there is no need to run additional power lines to the module.

Additionally, PoESP32 Unit is designed with secondary development in mind. It provides the necessary interfaces and capabilities for customization and expansion, allowing developers to tailor the module to their specific requirements.

    Really like

    I’m opening these up and flashing these to run ESPHome as well as Arduino sketches, using them as data collectors, and they are great for this. The uart port works as i2c if I need, no issues. Wish list, a jumper to disable the PoE if desired (or maybe M5 can tell us a trace or pin to cut, or component to remove)

    Most reliable ESP32

    Basically, it's the best ESP32 you can get yourself if you need reliability. POE is amazing, and so is this unit, even though it doesn't have any additional pin availability aside from the Grove port. 10/10 highly recommend, especially for ESPHome!

    Great Unit !

    The ESP32 Ethernet Unit with PoE is an excellent controller better than any other PnP device with full functionality of a non-PoE ESP32. Just fantastic...
