I have the basic SPDT relay Carrier with 5VDC Relay, and am trying to activate it with Raspberry Pi 3 B+ GPIO pins.
I have the GND connected to pin 9, which is ground.
I have tried connecting VD0 to pin 1 which is 3v, and pin2 which is 5v.
I have EN connected to pin 3.
The Raspberry pi’s GPIO pins output about 2.8v, I have confirmed this with a multimeter. This does not activate the relay, wether using 3v or 5v connected to EN.
When I connect VD0 and EN to the positive side of a 9v battery, and GND to the negative side, the relay activates fine.
What am I doing wrong here? Is there another relay I should be using?
