Hex Cube Black Flight Controller
PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.
TIP
The Cube Orange is the successor to this product. 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 Hex Cube Black flight controller (previously known as Pixhawk 2.1) is a flexible autopilot intended primarily for manufacturers of commercial systems. It is based on the Pixhawk-project FMUv3 open hardware design and runs PX4 on the NuttX OS.
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 form 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 contain detailed information, including an overview of the Differences between Cube Colours.
TIP
This autopilot is supported by the PX4 maintenance and test teams.

额定电压
Pixhawk can be triple-redundant on the power supply if three power sources are supplied. The three rails are: Power module input, servo rail input, USB input.
正常运行最大额定值
Under these conditions all power sources will be used in this order to power the system
- Power module input (4.8V to 5.4V)
- Servo rail input (4.8V to 5.4V) UP TO 10V FOR MANUAL OVERRIDE, BUT AUTOPILOT PART WILL BE UNPOWERED ABOVE 5.7V IF POWER MODULE INPUT IS NOT PRESENT
- USB power input (4.8V to 5.4V)
绝对最大额定值
Under these conditions the system will not draw any power (will not be operational), but will remain intact.
- Power module input (4.1V to 5.7V, 0V to 20V undamaged)
- Servo rail input (4.1V to 5.7V, 0V to 20V)
- USB power input (4.1V to 5.7V, 0V to 6V)

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 px4_fmu-v3_defaultIssues
CAN1 and CAN2 silk screen on the Cube Black are flipped (CAN1 is CAN2 and vice versa).
