I need to connect a Raspberry3 with a Carberry 2 and a HiFiBerry Digi+
Could you help me determine if the GPIOs are compatible and if all the 3 devices will work nicely together?
This is what I found on the HiFiBerry site:
GPIO2-3 are used by our products for configuration. If you are experienced with I2C, you might add other slave devices, if you are a novice, we don’t recommend this at all.
GPIOs 18-21 are used for the sound interface. You can’t use them for any other purpose.
I can't find the pinout scheme for Carberry 2 if it's the same of the first version the only pin overlapping is the number 3 and is indicated as "Future use".
Could you give me more info about the Carberry 2 GPIO pinout?
Thank you!
