Key features

• 32-bit ARM Cortex-M4 processor at 168MHz
• Triple-redundant IMU (2x accelerometer + 3x gyro)
• Barometer for altitude hold
• Multiple flight modes including GPS, loiter, RTL
• MAVLink protocol for ground station communication
• SD card slot for logging and parameter storage
• Multiple UART ports for GPS, telemetry, OSD

Good to know

• Requires GPS module for position hold and autonomous modes
• Install Mission Planner or QGroundControl for configuration
• Calibrate accelerometer, compass, and radio before first flight
• Motor PWM outputs are not servo-compatible – use servo rail for servos
• Safety switch must be pressed before arming
• Always test in ANGLE (self-leveling) mode before acro/rate mode
