mRo X2.1 – 777

The mRo X2.1-777 is the reduced version of PixHawk1 with better sensors and more flexibility. This board will “work out of the box” with PX4 and Ardupilot. Populated with the extremely powerful STM32F777 microcontroller.

With mRo you don’t have to buy and pay for an autopilot pilot that includes cables and accessories that you might not use. Maybe you need a bare board for a replacement, maybe you don’t need the pin headers soldered, maybe you want to save time, maybe you need everything, who knows? We give you the flexibility to choose what you really need/want and save some money in the way, we won’t judge!

Includes the following cable pack and pin headers (un soldered)
