Olimex Unveils ESP32-POE Board with… PoE Support

ESP32 Ethernet enabled boards are definitely in the minority however, and what’s even more difficult to find is an ESP32 board with Power-over-Ethernet (PoE) support. The good news is that if you’re looking for such type of board, Olimex is working on one based on requirements from their customers.
