Volumio with IQaudIO DAC Pro GPIO

Volumio Information

Volumio Version: 2.873
Hardware: 3B+

Using Pis IQaudIO DAC Pro board with my Pi 3B+ all works well.

I want to use the GPIO plugin (using the GPIO Button by Tom Passer) for song transport using tactile switches

The plugin page is not clear do I need resistors or not for the 3v line and how does this interact with the IQaudIO hat I understand some pins I cant use as the DAC uses them, thats correct?

The hat also uses the 3v line so can I still use it for volume control?

Welcome to Volumio raymate :slight_smile:

There is no easy answer to your question. But as a rule of thumb, questions w.t.r hardware are best answered by the manufacture of the hardware :wink:

The plugin knows nothing about the hardware connected, and hence you will have to look up the datasheet/ask the manufacture which pins are accessible.

Good luck!

The GPIO pins 2 … 8 are pulled high by default and just need a tactile switch to ground. With the other GPIOs it’s shown here (bottom of the page).

I2S DACs usually use the GPIOs 2, 3 and 4 which can’t be used otherwise then.
