Bosch BMI330 Extended Temperature IMU
Bosch BMI330 Extended Temperature Inertial Measurement Unit (IMU) is a high-performance 6-axis sensor designed for demanding industrial and harsh-environment applications. The Bosch BMI330 IMU integrates a 3-axis gyroscope and a 3-axis accelerometer, delivering precise motion sensing with low noise and high stability across an extended -40°C to +105°C temperature range. Engineered for robustness, the BMI330 features advanced built-in self-test capabilities, vibration robustness, and a low total cost of ownership (TCO) due to long-term stability and reliability. The IMU supports multiple digital interfaces (I3C, I2C, and SPI) and is optimized for applications such as robotics, industrial/agricultural, and navigation systems. The compact LGA package and Bosch’s proprietary Force-Operating Compensation (FOC) technology ensure consistent performance even under mechanical stress and temperature fluctuations. With a combination of precision, durability, and flexibility, the BMI330 is ideal for mission-critical motion sensing in challenging environments.
