The Pi-DACZero / DACZero Headphone
The Pi-DACZero is a smaller version of the IQaudIO Pi-DAC+ which is designed to be used with the
Raspberry Pi-Zero.
The Pi-DACZero delivers audio Line Out and uses the same Linux drivers as the Pi-DAC+.
There is an optional Headphone daughter card for the Pi-DACZero which can be mounted above the
DACZero to give an amplified headphone output in parallel. The Pi-DACZero and Pi-
DACZeroHeadphone boards are powered from the Raspberry Pi-Zero itself.
