PX4 Pixhawk V6X Autopilot APM Open Source Multirotor VTOL Flight Controller

Pixhawk V6X Autopilot APM Open Source Multirotor VTOL Flight Controller adopts the latest open-source FMU v6X architecture and STM32H7 processor, offering enhanced performance. Its improved protection grade, shock absorption design, and multiple sensor redundancy architecture ensure safe flight. Efficient heat dissipation and temperature compensation keep the flight controller in optimal working condition at all times. It keeps pace with the times, ensuring compatibility with the open-source ecosystem.

High-Performance Processor
STM32H753IIK6 Processor: Equipped with a double-precision floating-point unit (DSP & FPU) and a maximum clock speed of 480MHz, it provides powerful data processing capabilities, supporting complex algorithm computations and quick responses, laying a solid hardware foundation for flight control algorithms, navigation algorithms, and more.

Large Capacity Storage: With 2MB FLASH and 1MB RAM, the system has ample space to run complex operating systems, algorithms, and user-defined programs, while also supporting extensive data caching and processing.

High-Precision Sensor System:

• Aerospace-grade ICM45686 Gyroscope & Accelerometer: Utilizing the world’s first BalancedGyro™ technology, it significantly reduces sensor noise (gyroscope noise as low as 3.8 mdps/√Hz and accelerometer noise as low as 70 μg/√Hz), enhancing shock resistance and temperature stability, ensuring the accuracy and reliability of flight data.
• IMU Temperature Compensation System: Maintains sensors within the optimal operating temperature range through constant temperature compensation, reducing temperature drift and ensuring precise flight data in any environment.

Multiple Safety Guarantees:

• Triple IMU Redundancy Design: Utilizes two sets of ICM45686 gyroscopes and one BMI088 sensor in a non-similar redundancy configuration, providing multiple layers of protection to ensure stable operation of the flight control system even if some sensors fail.
• Safety Protection Mechanisms: Includes overcurrent and overvoltage protection, port ESD protection, remote control receiver current limiting protection, and power EMI filtering, offering comprehensive protection for the flight controller against external interference and damage.

Flexible Expansion and Compatibility:

• PWM Voltage Switching: Supports switching between 3.3V and 5V, accommodating more peripherals and specifically addressing signal attenuation and interference issues over long distances for larger models.
• Gigabit Ethernet Interface: Integrated gigabit Ethernet interface for easy connection to Raspberry Pi, NVIDIA Jetson series development boards, and other computing modules, enabling advanced functions such as SLAM modeling and visual tracking.
• DroneCAN Communication Protocol: Comes standard with the OnePMU power module, supporting the DroneCAN communication protocol for efficient power management and data transmission capabilities, meeting the needs of complex flight missions.

Efficient Heat Dissipation Design:

• Aluminum Alloy Shell and Standoff Design: Combined with thermal conductive adhesive, it effectively dissipates heat from the main control and power chips to the shell, ensuring long-term stable operation and enhancing overall reliability.

OnePMU Current Meter as a Perfect Partner for Flight Control:
The X6 flight controller comes standard with the OnePMU power module, using the DroneCAN communication protocol. It supports a 10-61V input via an XT90 connector, continuous current detection of 90A, instantaneous 120A, with voltage and current detection accuracy of 0.04V and 0.15A, respectively, and a multi-filter design for minimal power ripple.

Custom Sponge Built-in Vibration Damping Design:
Utilizes custom vibration-damping foam, combining various materials and thicknesses in hundreds of combinations, tested across multiple models, effectively filtering out high-frequency vibrations, reducing gyroscope noise, and enhancing flight stability.
