TL;DR: what is the amp draw of the PXFMini?
Recently started assembling some drones using the PXFMini and a Pi Zero W. To power them we have a 25-35C 3S lipo battery and a step down voltage regulator plugged into the power point of the micro usb port of the Pi. The voltage regulator (aka buck converter) is rated for 2.0 A nominal, 3.0 A. From googling, I've seen that the Pi Zero W uses up to 300mA. When attempting to power the Pi + PXF via usb, the voltage regulator is browning out. It worked when supplying just the Pi, but not the Pi + PXF. Does anyone know what the amp draw of the PXF is at idle without any peripherals?
I'm guessing I either need to buy a higher rated voltage regulator or the recommended power module.
