The Bosch BMA255 is a MEMS-based 3-axis accelerometer engineered for precise motion sensing in power- and space-constrained applications. Its 12-bit digital output provides accurate acceleration data across three axes, enabling detection of tilt, shock, vibration, and specific motion events. The sensor’s programmable bandwidth from 8 Hz to 1 kHz allows for optimization between noise performance and response speed.
Designed for robust performance, the BMA255 operates across a wide temperature range of -40°C to +85°C and features a 32-sample FIFO buffer to reduce host processor load. Its flexible supply voltage (1.62V to 3.6V) and separate I/O voltage (1.2V to 3.6V) ensure compatibility with a wide range of microcontrollers and system architectures, from 1.8V logic to standard 3.3V systems.
