Lilygo T-Internet POE Ethernet Board mit ESP32 und LAN8720A

The LilyGo T-Internet POE is an ESP32-based Ethernet development board with integrated Power-over-Ethernet (PoE) functionality. It is specifically designed for IoT, smart home, and industrial applications that require a reliable wired network connection with simultaneous power supply via PoE. At the heart of the board is an ESP32-WROOM module with 4 MB of flash memory, which supports not only Wi-Fi 2.4 GHz but also Bluetooth 4.2 BLE. The wired network connection is facilitated by the LAN8720A Ethernet PHY chip, while the Si3404 PoE-PD chip converts the 48V Ethernet voltage to 5V system voltage—ideal for stable and low-maintenance installations. The board features a USB-C port, a microSD card slot, as well as reset and boot buttons. With the optional CH340C downloader, the board can be programmed directly via USB. This combination makes the T-Internet POE a robust and flexible platform for edge devices, gateways, data loggers, or smart home controls with LAN connectivity.
