However I thought, that maybe an Arduino nano could do the job of getting the Voltage level ( https://www.arduino.cc/en/Tutorial/ReadAnalogVoltage ) to then push it to the Rock64 via GPIO

Caution, the Rock64's GPIO's run at 3.3V and the Arduino nano is 5v, so if you're going to connect them together you need to use a level shifter. Or you can do what I did, connect the Arduino via USB and then read the data over the serial port instead.
