Carrberry and ther shields GPIO compatibility

[sharpedge]

Hi,
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!

Hello,
- about the pinout: please consult this link: http://www.carberry.it/wiki/carberry:hw ... _interface
All the pins displayed are used by Carberry, the Others you can use as you want.

Also I put attached the electric diagram of our pinout.

let me know,
best regards,
at disposal.

Already saw that, i need help understanding if pin 3 is used or not because it's written "Future use"

HI folks,
I know this is an old thread but I am interested in building a head unit for my car using the Carberry. 1 major problem is the lack of digital out which is a deal breaker for me. Did this go anywhere? Is it possible to add another car to carberry evn though it seems that the pins in use overlap?

I apologize for these noob questions. I am new to raspberryPi so still trying to ramp up. I'm more of a software guy so doing linux parts is a piece of cake, it's the hardware that I am trying to figure out.
