Pixhawk6X Pro Internal Architecture

Key Design Points

  • High-performance ADIS16470 Industrial IMU with high accelerometer dynamic range (±40 g), perfect for accurate motion sensing in demanding UAV applications
  • All new advanced durable vibration isolation material with resonance frequency in the higher spectrum, ideal for industrial and commercial drone applications
  • High performance STM32H753 Processor
  • Ethernet interface for high-speed mission computer integration

Baseboards

The Pixhawk 6X Pro can be purchased with a number of baseboards (or no baseboard) to suit different use cases and vehicle types, including Standard v2A, Standard v2B, and Mini, which are shown below. It can also be used with any other Pixhawk Autopilot Bus (PAB) specification-compliant baseboard, such as the Holybro Pixhawk Jetson Baseboard and Holybro Pixhawk RPi CM4 Baseboard.

Features

Voltage Ratings

Pixhawk 6X Pro can be triple-redundant on the power supply if three power sources are supplied. The three power rails are: POWER1, POWER2 and USB. The POWER1 & POWER2 ports on the Pixhawk 6X uses the 6 circuit 2.00mm Pitch CLIK-Mate Wire-to-Board PCB Receptacle.

Normal Operation Maximum Ratings

Under these conditions all power sources will be used in this order to power the system:

  1. POWER1 and POWER2 inputs (4.9V to 5.5V)
  2. USB input (4.75V to 5.25V)

Absolute Maximum Ratings

Under these conditions the system will not draw any power (will not be operational), but will remain intact.

  1. POWER1 and POWER2 inputs (operational range 4.1V to 5.7V, 0V to 10V undamaged)
  2. USB input (operational range 4.1V to 5.7V, 0V to 6V undamaged)
  3. Servo input: VDD_SERVO pin of FMU PWM OUT and I/O PWM OUT (0V to 42V undamaged)

Voltage monitoring

Digital I2C battery monitoring is enabled by default (see Quickstart > Power).

INFO

Analog battery monitoring via an ADC is not supported on this particular board, but may be supported in variations of this flight controller with a different baseboard.

Building Firmware

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-v6x_default

Debug Port

The PX4 System Console and SWD interface run on the FMU Debug port.

The pinouts and connector comply with the Pixhawk Debug Full interface defined in the Pixhawk Connector Standard interface (JST SM10B connector).
