What 3DR Pixhawk mini is improved over the original?

3DR Pixhawk Mini, the next generation autopilot from 3DR. Building on the success of the original Pixhawk, 3DR Pixhawk Mini offers more in a 60% smaller package.

Pixhawk Mini is an upgraded Pixhawk designed in collaboration with HobbyKing and optimized to run the Dronecode PX4 firmware stack and QGroundControl multi-platform ground station (Windows, Mac, Linux, Android, iOS).

For just $199, Pixhawk Mini includes autopilot, GPS, and all the cables and connectors needed to get started building DIY quads, planes, rovers, and boats.

What’s Included?

• Pixhawk Mini Flight Controller

• GPS with uBlox M8N module with

  • Concurrent reception of up to 3 GNSS (GPS, Galileo, GLONASS, BeiDou)

  • Industry leading –167 dBm navigation sensitivity

  • Security and integrity protection

  • Supports all satellite augmentation systems

  • Advanced jamming and spoofing detection

  • Product variants to meet performance and cost requirements

  • Backward compatible with NEO‑7 and NEO‑6 families

• Integrated Power Module (up to 6s batteries) and power distribution board for quadcopters

• 8-channel servo output board for planes and other vehicles requiring powered PWM output.

•  Cables

  • 4 pin I2C cable and breakout board

  • 6 pin GPS+Compass cable

  • 6 to 6/4 ‘Y’ adapter for additional I2C devices

  • 4 JST to 6 DF13 cable for legacy telemetry radios

  • External safety switch cable

  • RCIN cable for PPM/SBUS input

  • 8 channel RC output cable

  • 6 pin power cable for included Power Distribution Board

What’s improved over Pixhawk 1?

• One third the size–dimensions reduced from 50 mm x 81.5 mm x15.5 mm to 38 mm x 43 mm x 12 mm. Smaller airframes can now operate autonomously without making sacrifices for the Pixhawk footprint.

• Rev 3 STM32 processor allow for full utilization of 2MB flash memory. 3DR Pixhawk Mini operates at only 50% compute capacity, 40 percentage points lower than the original Pixhawk. There is significantly more overhead available to run custom code.

• Improved sensors, including both primary and secondary IMU (MPU9250 and ICM20608, respectively), lead to much better vibration handling and increased reliability.

• GPS module included–Neo M8N with quad-constellation support and upgraded HMC5983 compass.

• Micro JST connectors replace DF-13. We can all breath a sigh of relief.

• Integrated piezo speaker and safety switch

What’s improved over Pixfalcon?

• Again, improved sensors, including both primary and secondary IMU (MPU9250 and ICM20608 respectively) for much better vibration handling and increased reliability.

• Dedicated CAN port for UAVCAN applications.

• Includes 8-channel servo output board for planes and other vehicles requiring powered PWM output.

• Includes I2C breakout board for a total of 5 I2C connections.

3DR Pixhawk Mini features an advanced processor and sensor technology from ST Microelectronics® and a NuttX real-time operating system, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle.
