# CubePilot Cube Orange+ Flight Controller
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.
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.
The manufacturer Cube Docs (opens new window) contain detailed information, including an overview of the Differences between Cube Colours (opens new window).

# Building Firmware
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:
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.
