Overview

Skip the Wi-Fi dropouts and wall adapters. The T-Internet-POE is an ESP32 development board with a built-in LAN8720 Ethernet transceiver and an onboard Power-over-Ethernet (PoE) module, so a single Ethernet cable delivers both a stable wired connection and power (36V–57V input) to the board.

That makes it a strong hardware base for anything that needs to be always on and always reachable — a Home Assistant or ESPHome node, a wired sensor hub, a gate or door controller, or any custom smart home build where Wi-Fi reception or spare power sockets are a problem. It still carries Wi-Fi and Bluetooth LE onboard too, so you’re never locked into wired-only.

Flashing and debugging are handled over USB Type-C, with a TF card slot for local storage/logging and RST/BOOT buttons for easy firmware work. It’s compatible with the Arduino IDE, PlatformIO, and ESPHome, with sample code available from LilyGO’s GitHub.

Note: a PoE-capable network switch or injector is required to power the board over Ethernet — this is not included.

Key features

  • ESP32 microcontroller with 4MB flash

  • Wi-Fi 802.11 b/g/n and Bluetooth LE 4.2 onboard
  • USB Type-C for programming and power
  • TF card slot for local storage
  • RST + BOOT buttons for flashing
  • Compatible with Arduino IDE, PlatformIO, and ESPHome

Product information

Use cases
  • Wired smart home hub or bridge
  • Run Home Assistant/ESPHome integrations on a rock-solid Ethernet link instead of relying on Wi-Fi coverage.
  • Remote sensor or controller nodes
  • Power and network a garage, loft, shed, or outbuilding sensor over one PoE cable, with no separate power socket needed.
  • Access/gate control or network relays
  • Always-on wired devices (door entry, gate automation, network bridges) that can't afford to drop off Wi-Fi.
