Pixhawk 2.4.8 PX4 32-Bit Autopilot Flight Controller

The Pixhawk 2.4.8 is a 32-bit open-source autopilot flight controller engineered for autonomous multirotors, fixed-wing aircraft, VTOLs, and ground rovers. Powered by an STM32F427 primary processor paired with a dedicated STM32F100 failsafe coprocessor, it provides redundant processing capability and deterministic real-time control for commercial surveying, agricultural spraying, and mapping platforms.

Key features

• Dual-processor architecture with an STM32F427 main MCU and an independent STM32F100 failsafe coprocessor for backup control.

• Full native compatibility with both ArduPilot (ArduCopter, ArduPlane, ArduRover) and PX4 autopilot software suites.

• Integrated sensor array including an InvenSense MPU6000 3-axis gyro/accelerometer and an MS5611 high-precision barometer.

• Comprehensive peripheral expansion with 5 UARTs, dual CAN bus interfaces, I2C, SPI, and dedicated ADC voltage/current sensing ports.

• Built-in MicroSD card slot for high-rate Blackbox data logging and post-flight mission analysis.
