Pin Map

You might have noticed that we used GP46 in hardware and GPIO 32 in our example code. This is because the MRAA library uses a different number for the pins. If you would like to use MRAA to control hardware, figure out which GPIO pins you plan to use on the table below (labeled "Edison Pin") and then use the MRAA Number in software.

The available pins on the Pi Block have been highlighted in yellow in the table.


  • Input/output voltage on the Pi Block is 3.3V
  • Input/output voltage on the GPIO Block is 3.3V by default
  • Input/output voltage on the Arduino Breakout is 5V
  • Input/output voltage on the Mini Breadboard is 1.8V
