3D Robotics Pixhawk

Pixhawk is an advanced autopilot system designed by the PX4 open-hardware project and manufactured by 3D Robotics. It features advanced processor and sensor technology from ST Microelectronics® and a NuttX real-time operating system, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle.

How It Works

• Advanced 32 bit ARM Cortex® M4 Processor running NuttX RTOS.
• Integrated backup system for in-flight recovery and manual override with dedicated processor and stand-alone power supply.
• Backup system integrates mixing, providing consistent autopilot and manual override mixing modes.
• Redundant power supply inputs and automatic failover.
• External safety button for easy motor activation.
• Multicolor LED indicator.
• High-power, multi-tone piezo audio indicator.
• MicroSD card for long-time high-rate logging.

Technologies

• 14 PWM/servo outputs (8 with failsafe and manual override, 6 auxiliary, high-power compatible).
• Abundant connectivity options for additional peripherals (UART, I2C, CAN).
• Microprocessor: 32-bit STM32F427 Cortex M4 core with FPU; 168 MHz/256 KB RAM/2 MB Flash; 32 bit STM32F103 failsafe co-processor.
• Sensors: ST Micro L3GD20 3-axis 16-bit gyroscope; ST Micro LSM303D 3-axis 14-bit accelerometer / magnetometer; Invensense MPU 6000 3-axis accelerometer/gyroscope; MEAS MS5611 barometer.
• Interfaces: 5x UART (serial ports), one high-power capable, 2x with HW flow control; 2x CAN; Spektrum DSM/DSM2/DSM-X® satellite-compatible input up to DX8 (DX9 and above not supported); Futaba S.BUS® compatible input and output; PPM sum signal; RSSI (PWM or voltage) input; I2C® SPI; 3.3 and 6.6V ADC inputs; External microUSB port.
• Power System: Ideal diode controller with automatic failover; servo rail high-power (7 V) and high-current ready; all peripheral outputs over-current protected, all inputs ESD protected.
