New Pixhawk-compatible board from HK


Just $67 and available now:

The PX4LITE is the next step in FC hardware with its powerful ST micro 32bit ARM Cortex core and massive I/O support. The PX4LITE is one of the most advanced autopilot systems available with support for almost any type of vehicle from a moon rover or a multirotor aircraft. Designed by the PX4 open-hardware project, it is supported by a number of development communities making this one of the most flexible and reliable platforms for vehicle control.

This Flight Controller has been changed from the original with the addition of an IMU which houses the safety switch, buzzer port, USB port and indicator light. This allows the IMU to be placed in a more convenient part of the platform for access to these components. Also removed from the original are non-common interface components.


Overall this is an excellent flight controller for your larger multi-rotors.

• Advanced 32bit ARM CortexM4 high performance processor, can run NuttX RTOS real time operating system
• 8 PWM/servo output
• Support auto and manual mode
• Micro SD card records flight data
• Removal of non-common components SPKT/DSM, CAN, AUX OUT ports
• Independent IMU Inertia control unit, built-in damping structure, can effectively reduce the vibration of copter
• External extend module integrate RGB LED indicators, Safety switch, Beep buzzer and USB module, greatly reduce installation space
• All interface (includes GPS/Telem/Power) are compatible with APM2.5/2.6/2/8

*PX4/Pixhawk is an independent, open-source, open-hardware project aiming at providing a high-end autopilot to the academic, hobby and industrial communities (BSD licensed)

*The reference to APM refers to the ArduPilot project, a family of open source autopilots based on the Arduino open source computing platform, developed by 3DR and the open source community. It consists of a choice of ArduPilot Mega (APM) electronics and a range of free software versions for different vehicles and is governed by an open source creative commons license.

  • Developer
    Jonathan is wrong and is confused between RAM Memory for program execution vs Flash Memory for program storage. The chip cited is the same as the other Pixhawks.
  • 100KM
    Is Jonathan's claim true about it not being able to fly the latest apm code??
  • Looks nice, but not all that 'lite'. I have an Airbot PX4MiniAIO on the way, which is 35x35mm and no heavy alloy case (which is optional) -- should be very 'lite' by comparison. But the HK one looks nice nevertheless
  • What would be the solution for Auto Gimbal Control with this unit?

  • I have this unit on a Tarot 650 Sport. I flies beautifully.

  • Too big for mini frames doesn't have aux pins for auto gimbal control, so cheapo naza eqivalent?

    Its possible to make it heaps more usefull by routing aux pins to unused motor outputs though!
  • It's rev c?

  • Similar one @GLB, much lighter

  • I'm happy to have systems that are bigger than the Pixfalcon.  Not all of us are building 250 racer quads.  It would be nice to have some full-featured options.

  • Nice thing is non DF13 connectors, but do not know its handling.

    And, there will some possibility of improvement on IMU suspension by our self:-)

    Not nice thing is bigger footprint than "PixFalcon Micro" and "Pixracer".
