PIXHAWK is an advanced autopilot system of 3DR. It features transparent for hardware and convenient for re-development. PIXHAWK integrates with two advanced processor, STM32F103 backup failsafe 32-bit co-processor provides for manual recovery and has its own power supply if one processor breaks down, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle.
Users can also adjust the configurations of PIXHAWK according to different use and hobbies for different vehicles. In recent years, as one of the cores of autopilot system, PIXHAWK has gained a profound popularity among developers and hobbyists for being practical, easy to handle, economical.
Features
1. Advanced 32 bit ARM Cortex® M4 Processor running NuttX RTOS (68 MHz / 252 MIPS Cortex-M4F) real-time operating system.
2. 14 PWM/servo outputs (8 with failsafe and manual override, 6 auxiliary, high-power compatible)
3. Abundant connectivity options for additional peripherals (UART, I2C, CAN)
4. Integrated backup system for in-flight recovery and manual override with dedicated processor and stand-alone power supply
5. Backup system integrates mixing, providing consistent autopilot and manual override mixing modes
6. Redundant power supply inputs and automatic failover
7. External safety button for easy motor activation
8. Multicolor LED indicator
9. High-power, multi-tone piezo audio indicator
10. Micro-SD card for long-time high-rate logging
PPM: PPM encoder module is used to translates up to eight PWM (pulse width modulation) signals into one PPM (pulse position modulation) signal with ATMEGA328 IC, allowing you to connect a PWM receiver to a PPM-compatible autopilot with one wire, which on the one hand reduce the interface of the main chip and on the other hand save the space on PIXHAWK. As a result, you’ll get faster processing and reduced points of error.
3DR Power Module
The 3DR Power Module is a simple way of providing your control board with data of the current consumption and voltage measurements of a LiPo battery so that the control board can estimate the remaining flight durations according to the remaining and power capacity and the real time current consumption calculated by the received data. This 3DR Power Module has the function of BES which can provide stable power supply to the control board.
