I currently have this relay, and it is a 5V relay (for the control circuit).
Seeing as how our GPIO pins are rated at 3V3, I connected constant 3V3 power to
Vcc and a GPIO pin to
In1 to actually control the relay. This works well, but seeing as how this relay expects 5V to control it, I'm worried that 3V3 could be an issue of under-powering the relay (possibly causes unexpected disconnects from the magnet?).
With that being said, there doesn't seem to be any 3V3 relay modules out in the wild.
Are my concerns valid?
