HS2667 TTGO T-Internet-POE ESP32-WROOM LAN8720A Chip Ethernet Adapter And Downloader Expansion Board Programmable Hardware
More Information: https://github.com/Xinyuan-LilyGO/LilyGO-T-ETH-POE 
 
Product Detail :
 
1. Compatible with PoE mode A (powered by data pair) and PoE mode B (powered by backup pair) and auto MDIX, allowing the use of straight and crossover Ethernet cables. 
2. 20 needle footprint with 3.3V, V+ power and 15 ESP32GPIO are available for your application.  
3. The compact 75mm by 40mm footprint is compatible with 4 mounting holes of ordinary M2.5 or 4-40 screws. 
 
4. A small programming/USB serial console sub-module has been created so that the Inter-POE module can be easily programmed to meet the user's application needs.
