GPIO pins available for use with Soundcard connected

Post by Tutters » Wed Sep 20, 2017 12:54 am

Hi,

I am looking for a GPIO pin map which shows the pins used by the soundcard, and therefore which ones are available for use while the soundcard is plugged in. I need to use some 3.3V inputs and outputs while recording through the soundcard so want to see if they are available.

Thanks

Hi there,

The GPIO pins used are listed in this post :

Regarding your use case, the 3.3V pins are shared on the GPIO header and should be fine for you to use as well (as long as you don't draw too much current).
