Title: ESP32-POE-ISO Strapping pins
Post by: SteveKey on April 16, 2025, 06:06:32 AM
Hello all,

On an ESP32-POE-ISO-EA-16MB board.

On the ESP32 GPIO0 and GPIO15 are strapping pins. Could I have problems if I install an external 10k pull up resistor in both of them? I want to use them as inputs through an optocoupler and I want to install external resistors.

Thanks!

It shouldn't be a problem. They are already pulled up by default.
