I am currently testing with a X4M200 module which i have just bought and when i connected the Arduino Mega 2560, X4M200 and Level shifter this way: https://www.xethru.com/community/resources/using-xethru-sensors-with-arduino.139/. My X4M200 module did not seem to work? I used a volt meter and tested the voltage from the X4M200 3.3V pin to the GND and it measures 3.1V. So, I was wondering what is the required voltage level for the X4M200 module to run? Also, is it possible to just connect it to 5V from the Arduino Mega 2560?
