Connect Button to NavIO2

Hello, I am currently working on a drone project. Here is my setup:

  • Raspberry Pi 3B+
  • NavIO 2

When Raspberry and NavIO are merged NavIO takes in all pins of the Raspberry. Shown here. I was wondering how is it possible to connect a button like here. Is there anything like an additional platine which I can mount on the NavIO, so I can extend Raspberry’s pins? Or should I use the pins provided by NavIO.

Hi @Paul9019,

You can connect the button to servo rail pins. Servo rail pins can be controlled as GPIOs.
