Pixhawk Black Cube integration with M2

Hi all I’m new to building drones and looking for some advice. I’ve been working as a surveyor for the past 7 years and decided I wanted to build my own fixed wing for mapping. I’m wanting to run a Pixhawk 2.1 black cube with the standard carrier board w/ ardupilot, Emlid Reach M2, and a Foxtech Map 02 camera. The Pixhawk is 3.3V, the M2 is 5.5V, the Foxtech is 8.4V, and the motor I plan to use needs an 11.1V 3S battery. Are the different voltage requirements going to be an issue? I don’t what to run everything on different power sources. I have another question. Is it okay to just use the M2 as the only GPS on the drone or do I need another? I apologize for these amateur questions, but I’m learning. Thanks in advance!

Hi Andrew!

Welcome to our community forum.

Reach M2 can be powered using drone’s battery only. Pixhawk Cube has a GPS1 and GPS2 JST-ports to connect and power M2.

Regarding the connection, you might find useful this Adrupilot’s page with Cube’s pinout, Pixhawk’s quickstart on wiring, Foxtech Map 02 wiring, and our guide on M2’s integration with Pixhawk.

Also, it is possible to use Reach M2 as the only GNSS receiver for Pixhawk. Though you need to take into consideration that a single M2 receiver in non-RTK mode will provide you with meter-level accuracy only.

However, according to the Foxtech’s camera description, it requires external 8.4V power supply. You need to connect it to battery somehow. Unfortunately, I’m unable to provide you with a ready solution. I would recommend contacting the manufacturer on that subject.
