LilyGO T-POE Pro ESP32-WROVER-E Ethernet RS485 PoE Expansion Board

Description

The LilyGO T-POE Pro is a feature-rich expansion board built around the high-performance ESP32-WROVER-E module, which combines dual-core processing with 802.11 b/g/n Wi-Fi and Bluetooth 4.2. It is engineered to bridge wireless IoT projects with robust industrial networking standards. The board incorporates a LAN8720 Ethernet controller for gigabit-speed wired LAN connectivity and a full-duplex RS485 transceiver for long-distance, noise-resistant serial communication commonly used in Modbus and SCADA systems.

Its integrated Power over Ethernet (PoE) functionality adheres to the IEEE 802.3af standard, allowing the board to be powered directly from a PoE switch or injector, eliminating the need for a separate power supply in deployed installations. This makes it ideal for ceiling-mounted sensors, remote gateways, or embedded control units where AC power is inconvenient. The board’s design includes accessible GPIO via pin headers and a connector for attaching TFT or e-paper displays, providing a versatile foundation for developing sophisticated IoT endpoints, industrial telemetry hubs, or smart building automation controllers.
