# CubePilot Cube Orange+ Flight Controller

注意

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

The Cube Orange+ (opens new window) flight controller is a flexible autopilot intended primarily for manufacturers of commercial systems.

Cube Orange

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.

# Building Firmware

注意

The firmware for Orange+ will be present in releases from PX4 v1.14.

To build PX4 for this target, open up the terminal and enter:

make cubepilot_cubeorangeplus

注解

The firmware for Cube Orange+ and Cube Orange are not compatible. Due to a power feature of the STM32H757 it required updates in NuttX (opens new window) and therefore a new board config, bootloader, build target, etc.
