I have a sensor that requires used of 5V as input to Vcc. But I dont see any 5V output pins on the NodeMCU 1.0(12E). Is there a way I could get 5V output pins?

Its not a duplicate question. I want a 5V output and not provide 5V input to NODEMCU.

  • I also did not know the Vin pin could be used for output; read the accepted answer from Majenko.

The VIN pin outputs 5V approximately (dependent on USB input voltage) from the NodeMCU board.

    On my boards, the Vin pin outputs 4.76V because there's a Schottky diode between Vusb and the Vin pin which drops the voltage (see the circuit diagram). This Vin is also quite noisy and is a poor power source for analog circuitry.
