Product Description

Low Drift Inertial Measurement Unit Sensor

Product Description

The GI200F-A0-IMU is an inertial measurement unit (IMU) based on micromachining technology (MEMS), with built-in high-performance MEMS gyroscope and MEMS accelerometer, outputting 3 angular velocities and 3 accelerations.

Main Functions

Three-axis digital gyroscope:
1. ± 500º/s dynamic measuring range;
2. Zero bias stability: 10 °/H (GJB, 10s), 2.0 °/H (ALLAN);
Triaxial digital accelerometer:
1. ± 16g dynamic measuring range;
2. Zero-bias stability: 0.5mg (GJB, 10s), 0.1mg (ALLAN);
High reliability: MTBF > 20000h;
Guaranteed accuracy within the full temperature range (-40 ℃~ 70 ℃): built-in high-performance temperature calibration and compensation algorithm;
Suitable for working under strong vibration conditions;
Interface 1 channel SPI, 1 channel UART.
