CubePilot Cube Orange+ Flight Controller

WARNING

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

The Cube Orange+ flight controller is a flexible autopilot intended primarily for manufacturers of commercial systems. Cube Orange+ is similar to Cube Orange, but has a more powerful dual-core processor (STM32H757, and some different sensors parts.

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.

The ADS-B carrier board includes a customized 1090MHz ADSB-In receiver from uAvionix. This provides attitude and location of commercial manned aircraft within the range of Cube. This is automatically configured and enabled in the default PX4 firmware.

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

Building Firmware

WARNING

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

INFO

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