Why use ESP32 if you're powering with PoE? Might as well use an "Ethernet-on-board" like Teensy 4.1, and then use a PoE splitter (ex: https://www.adafruit.com/p

Why pay for WiFi power (which is rather expensive) when you literally are sending Ethernet communication wires to your uC ?

- blutack 4y agoI use these https://www.olimex.com/Products/IoT/ESP32/ESP32-POE/open-source-hardware https://www.olimex.com/Products/IoT/ESP32/ESP32-POE/open-sou... - they support proper PoE as opposed to the dodgy passive stuff you usually end up with with splitters. Personally I'd take an ESP32 over a teensy 4.1 unless you specifically need the extra GPIOs or something. The teensy's are great hardware, but you're stuck with either Arduino or hand rolling. You don't pay for WiFi power if the RF amp is off, and ESP-IDF for me is far better to work with than the Arduino software ecosystem especially once the complexity starts going up. Also, if you just want to make widgets and not learn embedded development esp-home is brilliant.
