Mission Planner and the Holybro Pixhawk 4

Can the Holybro Pixhawk 4 use Arducopter software and Mission Planner?

Well, let’s see what the Holybro Pixhawk website has to say about that:’

Seems to be a link to Ardupilot hiding there…

Yes it can - but like Dave is showing it literally just takes a google search and maybe 30 seconds of research to figure that out.

There even seems to be a video that is your exact question answered!

I didn’t even know there was a Holybro Pixhawk4 website. This is good information though. After too many crashes, and now that the company has gone out of business, I need to change flight controller systems from Vector to a Pixhawk variety and Holybro looks good. Any other suggestions?

Many. Hex, CUAV, Holybro, Matek, Mro. In no particular order.
