Hi229
Hi229 integrates a 3-axis accelerometer, a 3-axis gyroscope, a 3-axis magnetometer, and a microprocessor. It is an inertial measurement unit (IMU) that can simultaneously output the 3-axis angular velocity, 3-axis acceleration, 3-axis magnetic field, quaternion and Euler angle after sensor fusing. You can tune the IMU to fit your application, for example, change sampling rate and sensor fusion mode (6-axis or 9 axis). Hi229 brings more possibilities to robots, unmanned driving, and AR/VR. The chip size is: 12×12×2.6mm, adopts 3.3V serial port output and is compatible with 5V TTL voltage.
Data fusion algorithm
Hi229 uses the exclusive data fusion algorithm. The high-performance raw data and the Euler angle and quaternion after sensor fusion have very small data delay and phase distortion (less than 2.5ms). We provide ANROT IMU GUI software to help you quickly evaluate and test.
USB evaluation board
You can buy our USB transfer module to quickly connect IMU to the host (ex. PC, raspberry Pi). Use our code examples in multiple programming languages to create your own applications
