Pixhawk Ardupilot
Introduction
Pixhawk is the world's most famous open source flight control hardware manufacturer 3DR launched open source flight control. Pixhawk as an open source hardware and has powerful features, reliable performance has been favored by the majority of users. The open source of hardware has caused many hardware manufacturers to join the ranks of manufacturing pixhawk. As the well-known open source flight control manufacturer in China, cuav uses the same hardware design and fully imported chips according to the original pixhawk design to produce the cuav. Pixhawk has a very high stability.
Cover all models
The Pixhawk is a drone control system that runs PX4 and ArduPilot environments.
Applicable model: plane\copter\helicopters\VTOL\unmanned vehicles\ unmanned boats.
Powerful processor
Based on STM32F427 (180MHZ) master and STM32F100 coprocessor.
Redundant design
-
Built-in two-group IMU redundancy design (including two groups of accelerometers, two groups of gyroscopes, one group of electronic compasses, and one group of digital barometers)
-
Support 3 sets of power supply redundant switch
-
Software built-in sensor data fusion mechanism and failover mechanism will greatly reduce the chance of crash caused by flight control.
Rich expansion
Scalable 1 set of electronic compass, 2 sets of NMEA or UBX standard GPS, CAN bus device (ESC), 2 I2C devices (smart battery, status light, optical flow smart camera, laser sensor, ultrasonic sensor, etc.)

Pixhack LED status lights (RGB three-color status lights)
Red and blue alternately flashing: Initialize the sensor, please balance the autopilot board
Blue flashing: locked state (satisfaction with auto-steady mode unlockable condition), but GPS has not yet succeeded in 3D FIX. If the autopilot mode requires GPS positioning, it will Failed to arm.
Blue is always on:The Autopilot have been Arm but no GPS
Flashing green: The Autopilot have been Arm (and meets unlockable conditions), GPS is also 3D FIX locked.
Fast flashing green: Search for high-precision SBAS GPS satellites. The Autopilot the locked state (and satisfies the unlockable condition), GPS is also 3D FIX.
Green is always on - The buzzer emits a long beep: The aircraft is unlocked and ready to take off
Double flashing yellow light: Unsuccessful arm (check Pre-Arm error message)
Flashing yellow alone: Failsafe activated
Yellow blue flashing: - High - High - High (low buzzer) (dah-dah-dah-doh): GPS fault or GPS failsafe activation
Red yellow flashing: disable Kalman filter or inertial navigation (error)
Purple yellow flashing: barometer fault
Solid red: Hardware error. Usually no TF card (reinsert TF card or replace), MTD device or IMU sensor is detected. You can view boot directory information for BOOT.txt.
Steady red, SOS sound: SD card lost or SD card format error After the power is turned on, no lights are on. Firmware/firmware lost; SD card lost or SD card malformed (ac3.4 or higher firmware)
