The ISM330IS is an iNEMO® industrial-grade 6-axis IMU (3-axis accelerometer + 3-axis gyroscope) from STMicroelectronics.

Core Resources

ISPU 32-bit RISC Processor (with FPU Floating-Point Unit)32 KB program memory + 8 KB data memory; supports C language and models trained via NanoEdge AI Studio.Sensor Hub: Supports connection of up to 4 external sensors (magnetometers, pressure sensors, etc.)Embedded temperature sensor, built-in self-test, programmable interruptsFIFO buffer for continuous data acquisition

Application Scenarios

Predictive equipment maintenance: Vibration anomaly monitoring for motors, fans and pumps. Real-time local analysis performed by ISPU, eliminating continuous raw data acquisition by MCU.Attitude detection and tilt positioning for small AGVs and mobile robots.Attitude feedback and collision recognition for collaborative robotic arms.Portable wireless condition monitoring nodes and battery-powered sensing terminals.Factory asset tracking and equipment attitude & shock logging.

Humanoid Robots & Smart Mobile Devices

Joint attitude sensing and gait recognition for humanoid robots.Gimbal stabilization (medium & low-speed scenarios; not suitable for ultra-high-speed rotation).

Key Selling Points

The ISPU supports C-language programming for flexible development. It can execute attitude calculation, FFT vibration analysis and AI fault identification, backed by a comprehensive ecosystem (X-CUBE-ISPU, NanoEdge AI).Ultra-low-power always-on mode, ideal for battery-powered wireless IoT nodes.On-chip Sensor Hub enables connection to magnetometers and other components for simple 9-axis solution integration.6-axis sensors fabricated on the same die for excellent data synchronization.Algorithm offloading inside the sensor reduces MCU computing load, cuts system power consumption and lowers communication latency.
