Inertial Measurement Unit: BMI330
Operates up to 105°C. Efficient. Easy to integrate.
BMI330
IMU combining accelerometer and gyroscope
Reliable in heat, efficient in power – the ultimate IMU. This sensing solution combines a high-precision accelerometer with a self-calibrating gyroscope, making it ideal for navigation, robotics, and industrial or agricultural applications. It operates in temperatures up to 105°C.This 6-axis IMU combines a 16-bit accelerometer and a self-calibrating 16-bit gyroscope in a 2.5 mm x 3 mm LGA package and is Pin2pin compatible with other Bosch Sensortec IMUs.The embedded feature sets and built-in power management unit (PMU) allow high performance at low power consumption.
