mRo Pixhawk (FMUv3)
PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.
The mRo Pixhawk® is a hardware compatible version of the original Pixhawk 1. It runs PX4 on the NuttX OS.
The controller can be used as a drop-in replacement for the 3DR® Pixhawk 1. The main difference is that it is based on the Pixhawk-project FMUv3 open hardware design, which corrects a bug that limited the original Pixhawk 1 to 1MB of flash.
Assembly/setup instructions for use with PX4 are provided here: Pixhawk Wiring Quickstart
This autopilot is supported by the PX4 maintenance and test teams.
