ERICCO INERTIAL TECNOLOGY ER-MIMU-044 Ultra-size OEM Attitude-control MEMS IMU Introduction Inertial Measurement Unit, referred to as IMU, is a device to measure the attitude angle (or angular velocity) and acceleration of the three axis of the object. Gyroscope and accelerometer are the core devices of inertial navigation system (INS). With the built-in accelerometer sensor and gyroscope, the IMU can measure the linear acceleration and rotation angular velocity from three directions and can obtain the attitude, velocity and displacement information of the carrier through the resolving. ER-MIMU-044 uses MEMS accelerometer and gyroscope with high quality and reliability, RS422 and external communication. Default baud rate 921600 (customized). With X, Y, Z three-axis precision gyro, X, Y, Z three-axis accelerometer with high resolution, can be output by RS422 X, Y, Z three axis of gyroscope and accelerometer's original hexadecimal complement data (including gyro hexadecimal complement the numerical temperature, angle, the accelerometer hexadecimal temperature, the acceleration hexadecimal complement number); It can also output float dimensionless values of the gyroscope and accelerometer processed by the underlying calculation. A simple operation is required to connect our products to your system and obtain IMU data without the 15-pin plug provided by our company. At the same time, the size and weight of our products can be significantly reduced by removing the base plate housing.

ERICCO INERTIALTECNOLOGY The user installs the test interface on the computer,open xInsConnect.exe, as shown below. Click "COMCFG" to configure the baud rate of RS422 serial port, which is the COM port required; Click the "Open" button to open the RS422 communication interface and power on the IMU. The Angle data of X,Y,Z gyro "GX,GY,GZ", the data of X,Y,Z accelerometer "ACCX,ACCY,ACCZ" will be displayed on the interface. The temperature data of IMU will be displayed in the "TX" box. Click "CAL" box to set the data update rate of the interface to 100. The "Counter" box displays the frame serial...

ERICCO INERTIALTECNOLOGY CQMCFG Open Close 1 installation error description Internal orthogonal compensation has been carried out for the whole product. If the platform used by the product cannot guarantee the accuracy of the benchmark after installation, please compensate the installation error accordingly. When the product is installed, it should be tightly installed parallel to the base level of the carrier installation (the installation error with the base level should be less than 0.05°). Because the product is a precision test instrument, although there is a shell protection, in order to...
