Tsvetan Usunov Turns the Olimex ESP32-POE Into a Low-Cost One-Wire Wi-Fi Gateway
Tsvetan Usunov, founder of the Bulgarian open-hardware specialist Olimex, has showcased a new use for his Espressif ESP32-based Power-over-Ethernet (PoE)-ready microcontroller development board family: turning it into a low-cost single-wire Wi-Fi gateway.
"Need to share a wired internet connection over Wi-Fi, but want a compact solution powered through PoE," Usunov asks, rhetorically, by way of introduction to his latest project. "Here's an interesting open-source project that transforms an ESP32-POE or ESP32-POE-ISO into a Wi-Fi NAT [Network Address Translation] router using the Arduino IDE."

The Olimex ESP32-POE takes Espressif's classic ESP32-WROOM-32 module and put it into a gumstick-like format with a wired Fast Ethernet port at the far end. This isn't just for network connectivity: as the name suggests, it offers IEEE 802.3-compliant Power-over-Ethernet (PoE) support — meaning that,...
