Hi, thought you may like to see a picture of the pre-production Pi-AMP (iqaudio.com/?page_id=34).
This Raspberry Pi sized Class D stereo amplifier delivers stunning audio quality - suitable for any audio project and particularly useful when combined with i2s based DACs such as the IQaudIO.com Pi-DAC with built in hardware volume control.
The IQaudIO.com Pi-AMP is based on the Texas Instruments TPA3118D2. We’ve focused exclusively on audio quality components throughout to deliver an exceptional sonic performance. It sounds fantastic - even with a simple 12v 1.5amp wall plug!
We expect to conclude the design and sign off for mass production in the coming weeks, ready for summer - at what we believe is a great price.
There’s no special Linux driver or similar needed but for those who wish to enable / disable the amp from under software control this is possible via one of the Pi’s GPIO.
