I got this Relay: Link
It's a 3V 3.3V Relay "Active LOW" and I want to use it with an Arduino Micro. So far I only had experiences with Box/Printrelais.
I want to power the relay via the 3V Pin of the Arduino and toggle between NC and NO via Pin 12.
I tried it and and worked. Setting Pin 12 to LOW activates the Relay on the NC position.
I am not sure however if this setup is safe for the Arduino and the relay? I think setting Pin 12 from LOW to HIGH puts out more then 3 Volts.
Does the 3V 3.3V Relay description only refer to the coil voltage and is it ok to toggle it via a Digital Out pin without additional resistors?
