The Bosch BMA255 is a compact, ultra-low power 3-axis accelerometer designed for modern consumer electronics and motion sensing applications. With a 12-bit digital resolution, it delivers accurate measurement of acceleration across three axes, enabling detection of tilt, motion, shock, and vibration. Its programmable measurement ranges (±2g to ±16g) provide flexibility for various applications such as smartphones, gaming devices, and wearable systems.
The sensor integrates an intelligent interrupt engine that supports motion-triggered events like tap detection, orientation change, and free-fall detection. Featuring both I²C and SPI interfaces, it ensures easy integration into embedded systems. With extremely low current consumption and a compact LGA-12 package, the BMA255 is ideal for battery-powered and space-constrained designs requiring reliable motion sensing performance.
