The aim is to bring the world of multichannel audio to Raspberry Pi without costing a fortune. The card, based on the TI PCM3168 chip, provides 6 single-ended inputs and 8 single-ended outputs at 96kHz. The analog sections are completely isolated from the Pi's power supply to minimise the effects of digital noise. The physical layout is designed to provide maximum flexibility for users who want to enclose the Pi and other components (e.g. amplifiers) in a custom case.
