Description
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.
