BMI270

Overview

The BMI270 is an ultra-low power 6-axis Inertial Measurement Unit (IMU) designed specifically for wearable and mobile applications. It combines a 16-bit triaxial gyroscope and a 16-bit triaxial accelerometer in a compact 2.5 x 3.0 mm LGA package. The sensor features a built-in power management unit and ultra-low current consumption, typically 0.685mA in normal mode for both accelerometer and gyroscope.

Why Choose This Part

The BMI270 stands out for its ultra-low power architecture, featuring a dedicated on-chip FIFO buffer and an integrated power management unit that reduces host processor overhead. It includes specialized features like Component Re-Trimming (CRT) for fast sensitivity error compensation and hardware synchronization of inertial and auxiliary sensors.

Applications

Getting Started

Engineers can evaluate the BMI270 using the Bosch Sensortec Application Board 3.0 or the BMI270 Shuttle Board. Integration is supported by the Bosch Sensortec sensor API available on GitHub, which provides C drivers for I2C and SPI communication. Ensure the 14-VFLGA package is handled according to moisture sensitivity level 1 standards during assembly.
