Hii, Is it possible to use the ESP32 VIN pin as a 5V output to power a 5V 2-channel relay for example?
And if it’s possible, is it safe?
In my design, before I use a 5V power source to power the ESP32 and the relay, I want to try out powering both the ESP32 and the relay with the USB port. I know that the ESP32 don’t have a 5V output pin as Arduino does, but I saw some projects using the VIN pin to power a 5V relay, but some other design used different power sources, one 5V for the relay and a USB power source for the ESP32.
So, is it possible or indeed safe to use the VIN pin as a power output?
