LilyGO T-Internet-POE — ESP32 Ethernet & Power-over-Ethernet Development Board
£23.99

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.

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.
