CubePilot Cube Yellow Flight Controller

WARNING

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.

The Cube Yellow flight controller is a flexible autopilot intended primarily for manufacturers of commercial systems.

The controller is designed to be used with a domain-specific carrier board in order to reduce the wiring, improve reliability, and ease of assembly. For example, a carrier board for a commercial inspection vehicle might include connections for a companion computer, while a carrier board for a racer could includes ESCs for the frame of the vehicle.

Cube includes vibration isolation on two of the IMU's, with a third fixed IMU as a reference / backup.

TIP

The manufacturer Cube Docs contain detailed information, including an overview of the Differences between Cube Colours.

TIP

Most users will not need to build this firmware! It is pre-built and automatically installed by QGroundControl when appropriate hardware is connected.

To build PX4 for this target:

make cubepilot_cubeyellow

Issues

CAN1 and CAN2 silk screen on the Cube are flipped (CAN1 is CAN2 and vice versa).
