    I am not sure what you question is. You can certainly add header pins if you like. The default EasyDigi only controls the TX side. If you want to avoid VOX (which is recommended) you can build your own COS circuit with an optocoupler. It’s entirely up to you so long as the basic circuit functions are there.

    My current setup is my RPi2 connected via USB sound card and cables to the EasyDigi. In addition to that, I have some GPIO headers connecting the RPi2 and the EasyDigi with accordance to the setup page. I was wondering if the GPIOs are necessary for VOX operation.

    A GPIO is not required for the VOX mode on the receive; however, the GPIO is required to operate the PTT function of the TX radio. Hope that helps.
