BMI055 Inertial Measurement Units

Bosch’s BMI055 IMU is an ultra-small, 6-axis inertial sensor consisting of a digital, triaxial, 12-bit acceleration sensor and a digital, triaxial, 16-bit, ±2000°/s gyroscope. The BMI055 allows very low noise measurement of angular rates and accelerations in three perpendicular axes, and thus senses tilt, motion, shock, and vibration in cellular phones, handhelds, computer peripherals, man-machine interfaces, as well as remote and game controllers.

With its ultra-small footprint of only 3 mm² x 4.5 mm² the BMI055 is unique in the class of low-noise inertial measurement units. On top, the BMI055 integrates a multitude of features that facilitate its use especially in the area of motion detection applications such as device orientation measurement, gaming, HMI, and menu browser control.

The Bosch Sensortec shuttle-board BMI055 is a PCB with a BMI055 inertial measurement unit (IMU) mounted on it. It allows easy access to the sensors' pins via a simple socket. As all Bosch Sensortec sensor shuttle boards have an identical footprint, they can be plugged into Bosch Sensortec’s advanced development tools (such as the development
board or application board). Of course, the BMI055 shuttle board can also be used for the users own implementations.
