Product Features

• Independently developed attitude-solving algorithm:

  • X/Y axis static accuracy: 0.05°

  • Z axis (yaw) maintains long-term stability without drift under non-magnetic conditions.

  • High precision.

• Serial port outputs real-time data including attitude angle, acceleration, angular velocity, magnetic field, and air pressure. Easy to use.

• Comes with a test host program for configuring module parameters. Simple and convenient.

• Provides STM32 development board example code for easy secondary development.

• Uses a 32-bit MCU with high-precision sensors for strong performance.

• Compact size with castellated hole interface, easy integration onto custom PCBs.
