ProtoDAC TDA1387 X8 project

[TheOldPresbyope]

It looks as though the Innomaker DAC Pro HAT should work (perhaps you can confirm), since it is a master DAC with two crystal oscillators and has a topside GPIO connector. Setup Moode so that it works with the Innomaker DAC. The Innomaker will then reclock the I2S, and the reclocked I2S will pass through to the topside GPIO. Install ProtoDAC to the topside GPIO.

Quick answer: yes, stacking the ProtoDAC on top of the Innomaker DAC Pro HAT does work.

However, there's a protrusion on the DAC (a terminal block for external power wires) which interferes with seating the two boards directly. One would want to insert a CPIO header extender between them.
