Dear all,
I've got an ESP32 Devkitc and I need to control a 5V relay through a GPIO pin.
I will supply 5V (using a battery and dc/dc converter) into the 5v pin of ESP32. The GPIO outputs is going to be 5V OR 3.3V?
In general is it possible to control a 5V relay with ESP32?
Thanks is advance

It's not possible but you can use simple logic level shifter.

Depends what relay. I was able to control 5V relay with multiplexer without any problems.
Also adding 3V optocoupler will allow such control
