Pixhawk 2.4.8 PX4 32-Bit Autopilot Flight Controller

The Pixhawk 2.4.8 is a 32-bit autopilot flight controller built for autonomous multirotors, fixed-wing aircraft, VTOLs and ground rovers. A dual-processor design pairs an STM32F427 main MCU with an independent STM32F103 failsafe co-processor for backup control, and the board runs both ArduPilot (Copter, Plane, Rover) and PX4 firmware.

Key features

• Dual-processor architecture: STM32F427 main MCU plus an STM32F103 failsafe co-processor.

• Native support for ArduPilot and PX4, covering autonomous multirotor, fixed-wing and rover platforms.

• Onboard InvenSense MPU6000 gyro/accelerometer and an MS5607 barometer for stable altitude hold.

• 5x UART, 2x CAN bus, I2C, SPI and dedicated ADC inputs for GPS, telemetry, airspeed and power-module wiring.

• Built-in microSD card slot for Blackbox-style logging and post-flight mission analysis.

• Accepts PPM, Futaba S.BUS and Spektrum DSM/DSM2/DSM-X receiver inputs.
