I have built a working Squeezeplayer / amp system, (Logitech Media Server, Squeezelite, Jivelite),
Based on the excellent Banana Pi / Pro image of Igor Pecnovnik. (This comes with I2S support )
DIYINHK I2S PCM 5102A DAC module, jumper wired to Banana Pro I2s pins
Sure Digital Volume Control
Sure Class D stereo Amp 2x50w
Meanwell 24V 6A power supply, ( Set to 20V, powering amplifier, Banana Pro, Sure Digital Vol control and 5 in TFT)
dc-dc 24v to 5v 3a converter (Banana Pro and Sata Drive Supply).
dc-dc 24v to 12v 3a converter (TFT and Sure Volume control supply).
3.5 in Sata Drive. (Music Library)
5in CVBS 800x480 TFT (Jivelite display)
To be completed:- IR control using FLIRC dongle.
All information required was found using Google.
NOTE WELL:- Only the Banana Pro exposes the neccessary I2S signals. This will NOT work with a Banana Pi!
