LILYGO T-POE Pro

Overview

The T-POE Pro is an upgraded version of LILYGO's T-Internet-POE development board, combining the power of the ESP32-WROVER-E module with both Ethernet connectivity and Power over Ethernet capability. This makes it ideal for applications requiring wired network connectivity without a separate power supply — a single Ethernet cable delivers both data and power.

The board uses the LAN8720 low-power Ethernet physical layer transceiver for reliable 10/100Mbps wired networking, while the ESP32-WROVER-E provides WiFi and Bluetooth wireless connectivity as well. The PoE module supports IEEE 802.3 af/at standard with an input voltage range of 44-57V, delivering 5V at up to 4A to power the board and connected peripherals.

Additional features include Reset and Boot buttons, an expandable LCD screen interface, and the CH9102 USB-to-serial chip for programming and debugging. With 16MB flash and 8MB PSRAM, the board has substantial memory for complex applications.

Firmware Compatibility

The T-POE Pro is fully compatible with Arduino IDE and ESP-IDF. The official LILYGO GitHub repository for the T-ETH series (LilyGO-T-ETH-Series) provides example code for Ethernet, PoE, and WiFi configurations.

Flashing Guide

1. Connect the board via USB Type-C cable (CH9102 driver may be required on some systems)
2. Install CH9102 drivers from the LILYGO GitHub if needed
3. In Arduino IDE, select "ESP32 Wrover Module" as the board
4. Choose the correct COM port and flash the firmware
5. Alternatively, use ESP-IDF with the standard ESP32 toolchain
