Hi,
on our UAV the pixhawk is mounted in a way that the USB port for flashing the firmware is not accessible without unmounting the board every time.
In order to avoid to unmount the board every time I need to flash the firmware, I was thinking to use the front usb port (connector J302).
Looking at the schematics (PX4FMUv2.4.5-3.pdf, page 3) it seems to be possible, but since hardware is not my realm I would prefer to ask before.
Is that possible? Are the USB conncectors J301 and J302 the same USB port?
What concerns me is that the J302 connector is labeled with DF13C-4P-1.25V. I don’t understand why it says 1.25 V, since the USB port nominal voltage is 5V.
Thank you.
