简介
The Pixhawk® 6C is the latest update to the successful family of Pixhawk® flight controllers.
Inside the Pixhawk® 6C, you can find an STMicroelectronics® based STM32H743, paired with sensor technology from Bosch® & InvenSense®, giving you flexibility and reliability for controlling any autonomous vehicle, suitable for both academic and commercial applications.
The Pixhawk® 6C's H7 microcontroller contain the Arm® Cortex®-M7 core running up to 480 MHz, has 2MB flash memory and 1MB RAM. Thanks to the updated processing power, developers can be more productive and efficient with their development work, allowing for complex algorithms and models.
The Pixhawk 6C includes high-performance, low-noise IMUs on board, designed to be cost effective while having IMU redundancy. 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.
The Pixhawk® 6C is perfect for developers at corporate research labs, startups, academics (research, professors, students), and commercial application.
Key Design Points
- High performance STM32H743 Processor with more computing power & RAM
- New cost-effective design with low-profile form factor
- Newly designed integrated 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

额定电压
Pixhawk 6C can be triple-redundant on the power supply if three power sources are supplied. The three power rails are: POWER1, POWER2 and USB.
Normal Operation Maximum Ratings
Under these conditions all power sources will be used in this order to power the system:
- POWER1 and POWER2 inputs (4.9V to 5.5V)
- 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 4.1V to 5.7V, 0V to 10V undamaged)
- USB input (operational range 4.1V 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
Pixhawk 6C uses analog power modules.

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-v6c_default调试接口
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).
