LILYGO T-ETH-Lite

Introduction

T-ETH-Lite is a versatile embedded development board powered by the ESP32 main controller, offering deep integration of Ethernet communication, local storage, and power expansion capabilities.

On the hardware side, it features 16MB Flash and 8MB PSRAM, providing ample space for data processing and buffering in complex applications. It incorporates the RTL8201 Ethernet module, enabling efficient network transmission via interfaces like ETH_POWER_PIN (IO12) and ETH_MDIO_PIN (IO18), and includes a POE expansion interface to simplify power deployment.

The board offers extensive GPIO resources (covering GPIO02 to GPIO39), supports multiple ADC signal inputs (such as ADC1_CH0, ADC2_CH4), and capacitive touch functions (TOUCH02–TOUCH09). A TF card slot (with SD_CS on IO05) is also included for local data storage.

Designed for both industrial-grade stability and IoT flexibility, T-ETH-Lite is well-suited for intelligent control, remote monitoring, and automation systems, addressing scenarios that demand high reliability, low latency, and multi-peripheral collaboration.
