BMA250E Sensor Accelerometer and Shuttle Board

BMA250E Sensor Accelerometer

Bosch Sensortec's BMA250E accelerometer is an advanced, ultra-small, triaxle, low-g acceleration sensor with digital interfaces, aiming for low-power consumer electronics applications. Featuring 10-bit digital resolution, the BMA250E allows low-noise measurement of accelerations in three perpendicular axes. On top, the BMA250E with its 2 mm² x 2 mm² footprint integrates a multitude of features that facilitate its use especially in the area of motion detection applications, such as device orientation detection, gaming, HMI, and menu browser control. Featuring a full operation current consumption of only 130 µA, the BMA250E is ideally suited for mobile consumer electronic devices.

BMA250E Shuttle Board

Bosch Sensortec's BMA250E shuttle board is a PCB with a BMA250E acceleration sensor 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. Of course, the BMA250E shuttle board can also be used for customer's own implementations.
