I'm using it with nodeMCU and it works great. Simply, make sure to link it to the right pin. This relay is also small enough

Q: can I use this 5v relay with NodeMCU that has only 3,3V pin? thanks

BG223474445 NoI have tried it, because you need about 70ma and at 4.2volts minimum to actually do something(I have tried with an 18650 battery). So no but you can use it with an Arduino because they can provide enough current and voltage(5v) to power 8 relays (I've tried) so your best bet is to try an Arduino and add the NodeMCU as the Wi-Fi.

ligiomak I don't think so! I had to charge it every two days and my humidity sensor didn't change values after using it... I'd not suggest buying it
