PIXHAWK PX4 is an advanced autopilot system. With this excellent system, PIXHAWK PX4 Combo is surely a good choice for you to DIY a outstanding quad copter. It features high-performance processor, NuttX RTOX real time operation system, delivering incredible performance, flexibility and reliability for controlling any autonomous vehicles.
PIXHAWK PX4 ComboPIXHAWK PX4 Combo provides automatic and manual modes. The bus interface supports UART, I2C, SPI and CAN. It has redundant power supply input and failover ensuring your quad copter to work normally when facing unpredictable troubles. The integrated backup system also aims to keep copter safe. When the main controller loses efficacy, the system will safely alter to back up control. Besides, the external safety button is set for easy motor activation.

One of its highlights is that PIXHAWK PX4 Combo adopts the newest Ublox NEO-M8N GPS which is much better than LEA-6H GPS, giving more precise position. Multicolor lights represent different parts of the drone, letting you know each component’s working condition. In addition, the built-in micro SD card will records your flying data.
