:::warning PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues. :::
Pixhawk V6X® is the latest update to the successful family of Pixhawk® flight controllers designed and made in collaboration with CUAV® and the PX4 team.
It is based on the Pixhawk® Autopilot FMUv6X Standard, Autopilot Bus Standard, and Connector Standard.
:::tip This autopilot is supported by the PX4 maintenance and test teams. :::
Pixhawk® V6X brings you the ultimate in performance, stability and reliability in all aspects.
Arm® Cortex®-M7 processor (STM32H753) with Floating Point Unit (FPU), 480MHz high-speed operations and 2MB flash. Developers can be more productive and efficient, allowing for more complex algorithms and models.
High-performance on-board, low-noise IMU and automotive-grade magnetic compass based on FMUv6X open standard. It aims to achieve better stability and anti-interference ability.
Triple redundant IMU & double redundant barometer on separate buses. When the PX4 Autopilot detects a sensor failure, the system seamlessly switches to another to maintain flight control reliability.
An independent LDO powers every sensor set with independent power control. A vibration isolation System to filter out high-frequency vibration and reduce noise to ensure accurate readings, allowing vehicles to reach better overall flight performances.
External sensor bus (SPI5) has two chip select lines and data-ready signals for additional sensors and payload with SPI-interface.
Integrated Microchip Ethernet PHY for high-speed communication over Ethernet with onboard devices such as mission computers.
Newly designed vibration isolation system to filter out high frequency vibration and reduce noise to ensure accurate readings.
IMUs are temperature-controlled by onboard heating resistors, allowing optimum working temperature of IMUs
Modular flight controller: separated IMU, FMU, and Base system connected by a 100-pin & a 50-pin Pixhawk® Autopilot Bus connector.
The Pixhawk® V6X is ideal for corporate research labs, academic research and commercial applications.

Pixhawk V6X can be triple-redundant on the power supply if three power sources are supplied. The three power rails are: POWERC1/POWER1, POWERC2/POWER2 and USB.
POWER C1 and POWER C2 are DroneCAN/UAVCAN battery interfaces (recommended)；POWER1 and POWER2 are SMbus/I2C battery interfaces (backup).
POWER C1 and POWER1 use the same power switch, POWER C2 and POWER2 use the same power switch.
Normal Operation Maximum Ratings
Under these conditions all power sources will be used in this order to power the system:
POWER C1, POWER C2, POWER1 and POWER2 inputs (4.75V to 5.7V)
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.
POWER1 and POWER2 inputs (operational range 4.7V to 5.7V, 0V to 10V undamaged)
USB input (operational range 4.7V to 5.7V, 0V to 6V undamaged)
Servo input: VDD_SERVO pin of FMU PWM OUT and I/O PWM OUT (0V to 42V undamaged)
Voltage monitoring
Digital DroneCAN/UAVCAN battery monitoring is enabled by default (see Quickstart > Power).
:::note 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. :::
:::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:
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).
