What is it?

The wESP32™ is an ESP32-based core board with wired Ethernet connectivity and power over Ethernet (PoE) that was designed to help you quickly create zero-setup, single-wire-installation, connected devices. By combining a powerful microcontroller with excellent community support with 13 W of available power, reliable connectivity and a compact footprint, the wESP32 gives you a head start in your next IoT design and lets you focus on your application.
