ProtoDAC TDA1387 X8 project

He should replace a defective module.

I have not found a schematic for the modules.

Module pins 2 and 4 should connect to chip pin 1 BCK. Module pin 1 connects to chip pin 2 WS or LRCK. Module pin 3 connects to chip pin 3. Module pin 5 connects to chip pin 4 (ground). Module pin 28 connects to chip pin 5 (Vdd or 5V). The smaller 100nF caps connect across chip pins 4 and 5. The larger 1uF caps connect between chip pin 7 and ground (no module pin connection for chip pin 7, unfortunately). Module pin 6 connects to chip pin 8 (right channel out) and module pin 25 connects to chip pin 6 (left out). All chips are in parallel, except pin 7s which are independent.
