# Hex Cube Black Flight Controller

Warning PX4 不生产这款且也不生产任何自动驾驶仪。 若需要硬件支持或咨询合规问题,请联系 制造商 (opens new window)

The Hex Cube Black (opens new window) 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 (opens new window)FMUv3 开放硬件设计,在 NuttX (opens new window) 操作系统上运行 PX4。

Cube Black

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.

Note The manufacturer Cube Docs (opens new window) contain detailed information, including an overview of the Differences between Cube Colours (opens new window).

Tip This autopilot is supported by the PX4 maintenance and test teams.

# 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)
  • USB power input (4.8V to 5.4V)

# 绝对最大额定值


  • 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)
