Inertial Measurement Unit: BMI330
The BMI330 is a general-purpose, low-power Inertial Measurement Unit (IMU) designed to operate in temperatures up to 105 °C. It delivers fast and accurate inertial sensing for a wide range of applications, with a particular focus on harsh environments such as smart agriculture, industrial settings, and robotics. Its integrated feature set makes integration straightforward.
- Operates up to 105°C
- Engineered for rugged use
- Built-in power management unit (PMU)
