PIXHAWK intergrated the newest 32 bit chip technology and sensor technology, get rid 
of the dilemma of having only 8 bit CPU of APM, and CPU occupancy being too high.

Real time operation system
14 PWM/ Servo Output
Bus interface(UART,I2C,SPI,CAN)
Intergrated back up power and lose efficacy controller, main controller lose 

Efficacy can safely alter to back up control
Providing automatic and manual mode
Providing redundant power supply input and failover
Multicolor LED light
Providing multi sound buzzer interface
Micro SD records flying data
