Pin 3 in CON1 - input 5V stabilized voltage from [power board|http://remoteqth.com/wiki/index.php?page=Raspberry+PI+GPIO+interface+board] This pin may be connected with pin4 CON1, then the voltage measurement uses a common 5V voltage from the power supply module. The entire module can be powered from USB only, but there is a voltage drop, it is better to use an external source, or a DC/DC converter.
