ISM330DHCX 6 DoF IMU Breakout Board Adafruit ISM330DHCX 6 DoF IMU Breakout Board is based on the STM ISM330DHCX, an industrial quality accelerometer, and gyroscope 6-DOF Inertial Measurement Units ( IMUs). This IMU sensor has 6 degrees of freedom - 3 degrees each of linear acceleration and angular velocity at varying rates within a respectable range. The accelerometer has a ±2/±4/±8/±16g at 1.6Hz to 6.7KHz update rate. For the gyroscope, the update rate is ±125/±250/±500/±1000/±2000/±4000dps at 12.5Hz to 6.7KHz. This sensor has extra calibration and compensation circuits, giving it excellent performance in a wide environmental range from -40 to +105°C. The accelerometer and gyroscope are on the same silicon die, keeping the 6 measurements synchronized better than when the two sensors are on separate dies.
