I have a Parrot Mambo FPV. I’m trying to connect a 1.7 volt nrf52840 USB dongle via the mini USB port so that it can be powered by the UAV’s battery.
It doesn’t seem to work. Is this possible?
nope.
why not?
Because the USB port is not a powered Host port, current is only going TO the drone FROM a USB source, and not the other way around.
Are there any VCC or GND pins I could wire the chip to?
