ProtoDAC TDA1387 X8 project

The UcPi Universal Ultracapacitor power supply looks interesting. Since the ultracapacitors are preinstalled, that seems like a better value. The design is interesting or odd. It has the spring contacts for the RPi on the opposite side shown in the picture. So if you add your stack as described in the manual, the board would be flipped over (ultracaps on the bottom) and this also puts the ON/OFF switch as well as the green terminals on the bottom side. It seems better to use it as a standalone board without your stack mounted on it as designed. I guess the green terminal could be desoldered and moved, maybe the switch as well.

"Pi (any version), FifoPi Q7, ProtoDAC, and PurePi II with 5V going separately to Q7 and ProtoDAC" You meant 5V separately to RPi and ProtoDAC. Q7 requires 3.3V. This should be the better option of the two.

It's very nice that the clocks can be changed on MA.
