I’m looking to create a mini media centre with the PiScreen and a DAC such as IQaudIO (http://iqaudio.com/?page_id=454). However I’m not sure if I can use both at the same time as they both rely on the GPIO pins. Is there overlap with actual pin usage (which might be solvable with careful soldering) between the DAC and PiScreen or are there other DAC/screen combinations that I should be considering?
