Operating Environment: Temperature range of -40~80 ℃ for operation and -55~105 ℃ for storage.

Product Composition and Working Principle
The unit consists of a three-axis MEMS accelerometer and gyroscope. Data is collected via ARM microcontroller and digital interfaces, with calibration and compensation performed in software.

Electrical Interface
The unit uses an MW12-03-G-D-130-112 output with a Samtec CLM-112-02-L-D connector. Pin definitions include power supply, ground, and RS422 communication lines.

Communication Protocol
Utilizes RS-422 serial interface with a default baud rate of 921600bps and a data refresh rate of 400Hz. Data output includes angular rates, accelerated speeds, and temperature.

Test Interface Operation
Users can configure the RS422 serial port and view gyro and accelerometer data via a computer interface. The interface also displays IMU temperature and data frame serial numbers.

Precautions for Use
Ensure accurate installation with less than 0.05° error. Handle the unit gently to avoid damage and maintain accuracy.

After Sale
