Overview

Product Overview

The TTGO T-Internet-POE is an ESP32 Ethernet development board built for wired IoT networking, letting you create connected controllers, gateways, web servers, and remote monitoring nodes with Power over Ethernet support. Using the ESP32 with a LAN8720A Ethernet PHY, it delivers stable LAN connectivity for projects where Wi-Fi is unreliable or undesirable, including MQTT devices, Ethernet-enabled sensors, and data loggers on local networks. Compatible with Arduino, ESP-IDF, and common ESP32 workflows, it suits home automation, robotics, and industrial prototyping, while leaving the MCU available for GPIO, I2C, SPI, and UART peripherals.
