Building Test Tools for ORxPi Receiver

Testing voltage drops on Raspberry Pi 2

For smooth operation the voltage on Raspberry Pi 2 board should be in between 4.75 and 5.25 volts.

Test Case:
Voltage drops below 4.75V on Raspberry Pi 2 board

What you need:

  1. Arduino UNO board
  2. USB A-to-B cable
  3. Hookup wires
  4. Computer with Arduino IDE installed

Using hookup wires,

  1. connect PRi2 GIPO pin 2 with Arduino analog pin A0.
  2. connect RPi2 GIPO pin 6 with Arduino GND

Uploading Sketch:

  1. Connect your Arduino with PC using USB A-to-B cable.

  2. Upload the following Arduino sketch in to your Arduino UNO board.

    void setup()

    void loop()
    int gipoVoltage = analogRead(A0);

    float voltage = gipoVoltage * (5.0 / 1023.0);




  1. Open Arduino Serial Monitor from the Arduino IDE.
  2. Power up to start the ORxPi receiver.
  3. The Arduino Serial Monitor will continually display the voltage on Raspberry Pi 2 board.
