Is it possible to use such a power supply?
Good day.
There is a NodeMCU board and AC / DC (Zelo-module).
Relay control requires 5V current. But the NodeMCU board has only 3.3V.
Can I power Troyka contacts in this way?
Power (V) to 5V and G to GND, which go through the output connector of the converter. And throw the yellow wire (S) on the NodeMCU pin for logic (1 or 0) to control the relay.
