External Power Supply To Relay at Werner Annie blog

External Power Supply To Relay. To use multiple power source, it need to follow the following conditions: In these cases, we must use the external powers for sensors/devices. Must connect gnd of the external power supply to gnd of arduino. How to connect to the external power supply. Ive seen relays with vcc and jvcc (dont know what that is), but mine only has this. The reason i am writing is i was curious about hooking up a higher external power supply, can i hook up a 120v to the 4channel 5v. Looking at how to connect up power to the power relay board, if the power is not coming from arduino (in my situation) it’s the relay. You connect the external psu to the vcc and gnd pins on the relay board. You must also have a common ground connection between the external psu and the nodemcu. Must not connect 5v of the external power supply to 5v of arduino. Ideally, it is recommended to power the relay using an external power source. I want to operate a relay with an arduino uno, but i want to use a separate power supply for the relay.
