Hello friends, I hope you all are doing great. Today, I am going to share the Olimex ESP32-POE Library for Proteus . The ESP32-POE is a small red board from Olimex with an ESP32 and something most ESP32 boards do not have: a real Ethernet jack that also carries its power. One network cable feeds the board and connects it, so there is no power supply to hide and no Wi-Fi to fail. With this library the board runs your ESP32 Arduino sketch in Proteus 8.5, and ETH.begin() brings up the cable just as on the real hardware.
