We purchased the PXFmini board but we think it might be faulty.
We have connected it to a Raspberry Pi Zero W with the OS image provided and we have installed all the necessary software in order to make it works with ArduCopter. Unfortunately, after rebooting the system multiple times, the ardupilot system wasn't working and the LEDs were not correctly lighting up.
Since we have already purchased a PXFmini board before, we changed to the other one and it started working as expected.
Could you please indicate us how to get the replacement for the PXFmini board?
