Overview

The LILYGO T-ETH Lite is a compact and affordable Ethernet-enabled development board available in two MCU variants. The ESP32 version uses an ESP32-WOVER-E module with an RTL8201 Ethernet controller, while the ESP32-S3 version uses an ESP32-S3-WROOM-1 module with a W5500 Ethernet controller. Both variants include 16MB flash and 8MB PSRAM.

Both versions offer wired Ethernet connectivity alongside integrated 2.4 GHz WiFi and Bluetooth, making the T-ETH Lite ideal for applications requiring reliable wired network connectivity with wireless fallback. A TF card slot is included for local storage. Reset and Boot buttons support standard ESP32 programming workflows.

Optional accessories expand the board's capabilities: the Camera Shield ($11.24) adds camera functionality to the ESP32-S3 variant, while the POE Shield ($11.43) enables Power-over-Ethernet for cable-only deployments. The board is well-suited for network gateways, home automation hubs, industrial controllers, and any IoT application requiring stable wired connectivity.

Firmware Compatibility

  • Arduino: Supported via Espressif Arduino core with Ethernet library support for both RTL8201 and W5500.
  • ESP-IDF: Native framework with full Ethernet hardware support.
  • ESPHome: Compatible with Ethernet component configuration.
  • Tasmota: Supported with Ethernet-enabled build.

Flashing Guide

  1. Connect the T-ETH Lite to your computer via USB-C cable.
  2. Hold BOOT, press RESET, release RESET, then release BOOT to enter download mode.
  3. In Arduino IDE, select ESP32 Dev Module (for ESP32 variant) or ESP32S3 Dev Module (for S3 variant) with 16MB flash.
  4. Upload the firmware.
  5. Connect an Ethernet cable to the RJ45 port for wired network access.
  6. For PoE deployments, attach the POE Shield and connect a PoE-capable switch or injector.
