2.3.2 BMA280: Three-Axis Acceleration Sensor
The BMA280 is an advanced, ultra-small, triaxial, low-g acceleration sensor with digital interfaces,
aiming for low-power consumer electronics applications. Featuring 14-bit digital resolution, the
BMA280 allows very low-noise measurement of accelerations in three perpendicular axes and thus
senses tilt, motion, shock and vibration in cellular phones, handhelds, computer peripherals, man-
machine interfaces, virtual reality features and game controllers.
