Cube Flight Controller

The Cube flight controller (previously known as Pixhawk 2.1) is a flexible autopilot intended primarily for manufacturers of commercial systems. 它基于 Pixhawk 项目的 FMUv3 开放硬件设计，在 NuttX 操作系统上运行 PX4。

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.

Power System and Protection

Ideal diode controller with automatic failover
Servo rail high-power (max. 10V) and high-current (10A+) ready
All peripheral outputs over-current protected, all inputs ESD protected

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)
