IIM-46230 (TDK InvenSense SmartIndustrial™ Industrial-Grade 6-Axis IMU Inertial Module)

> It is a finished module (not a bare die), with a completely different market positioning from the ICM‑42607 (bare‑die IMU). It features built‑in SensorFT fault‑tolerant redundancy and is optimized for inertial navigation and attitude measurement in harsh industrial environments.

## Key Specifications

- Axes: 6-axis (3-axis gyroscope + 3-axis accelerometer)

- Package: 23×23×8.5 mm, 20-pin connector module for end-equipment mounting

- Power Supply: VDD / VDDIO = 3.0 ~ 3.6 V

- Gyroscope

  - Programmable Full-Scale Range: ±250 / ±500 / ±1000 / ±2000 dps

  - Bias Instability: 4.1 °/hr (typical)

  - Noise Density: 3 mdps/√Hz

- Accelerometer

  - Programmable Full-Scale Range: ±2g / ±4g / ±8g / ±16g

  - Noise Density: 70 μg/√Hz

- Interfaces: SPI, UART; supports incremental angle and incremental velocity output, microsecond timestamp, and PPS/GNSS timing synchronization

- Operating Temperature Range: -40℃ ~ +85℃

- Key Features: SensorFT™ fault-tolerant technology with internal multi-sensor redundancy and fault alarm. Single-point failure will not cause immediate system crash. Factory full-temperature calibration (bias, sensitivity, cross-axis, G-sensitivity).

## Applications

✅ Construction Machinery: Attitude and navigation for excavators, loaders and construction vehicles

✅ Precision Agriculture: Autonomous farm machinery and farm equipment attitude monitoring

✅ Industrial robots, AGVs, stabilized gimbals

✅ Surveying, geological exploration, geolocation (inertial dead reckoning when GNSS signal is lost)

✅ Attitude monitoring for UAVs, special vehicles and offshore platforms

> 

> Positioning Note: The higher-performance model IIM-46234 in the same series delivers gyro bias instability of 1.9 °/hr with higher precision and higher cost. The IIM-46230 is the cost-effective option within the product family, covering most industrial navigation requirements.

## Quick Comparison with ICM-42607 (your regularly promoted part number)

- ICM-42607: Bare LGA chip, compact footprint. Customers design PCB on their own. Target consumer and general industrial applications; no redundancy or fault tolerance.

- IIM-46230: Finished module ready for direct integration into end devices. Built-in redundancy and fault tolerance. Suitable for high-vibration industrial navigation projects requiring high reliability, at higher cost and larger size.
