3V relay Control Direct from ESP32 GPIO

[jahanzaibi]

Can we trigger the relay from the ESP32 GPIO , the relay is directly connected with the board and its not a Relay Module.
its a 3V songle relay., looks like the amp coming from the gpio is not enough to trigger the relay.

In general, that's a very bad idea as back-EMF of the relay coil can kill the ESP32. Suggest you use a transistor/mosfet to turn it on, as well as a flyback diode for back-EMF protection.
