ProtoDAC TDA1387 X8 project

Correct, the current limit of the LT1963 is 1.5A, so it would not be able to power the other RPis. Everything seems to be running fine with the Zero W/Kali/ProtoDAC. No undervoltage warnings.

For the Zero W/Kali/ProtoDAC stack about 8 hours. I am going to run the Zero W on a separate power supply and estimate time with Kali/ProtoDAC. Kali has a jumper that splits the RPi and Kali supplies. I am pretty sure ProtoDAC alone would run for days on a charge.

Thanks for the update. I’m planning on running only the ProtoDAC since the Q7 doesn’t have the 5v output.
