# Cube Orange Flight Controller
PX4 does not manufacture this (or any) autopilot. Contact the [manufacturer](https://cubepilot.org/#/home) for hardware support or compliance issues.
The PX4 dev team supports this flight controller as a footprint compatible replacement for Cube Black. We recommend however to consider products built on industry standards, such as the Pixhawk Standards. This flight controller is not following the standard and uses a patented connector.
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.
