Power on GPIO

Hello,
I have a robot project with multiple Rasperry Pi Zero W’s with Phats in it. I want to consolidate them onto 1 Pi3b+.

PZw1: Envirophat
PZw2: phat DAC and Phat Beat
PZw3: Adafruit PWM controller

There doesnt appear to be any GPIO conflict that I could see. But I ddin’t know if I would max out the power to all of them being supplied by the GPIO. Any thoughts on power draw from these combined boards?

Also can the Phat DAC/Phat Beat board stack be run on a ribbon cable? And if so what length?

Thanks in advance,
Duncan
