IAM-20680HP High-Performance Automotive 6-Axis Motion Tracking Sensor

## I. Official Name

IAM-20680HP (Brand: TDK/InvenSense)

Full Name: High‑Performance Automotive 6‑Axis Motion Tracking Device

Chinese: High-performance automotive 6-axis motion tracking sensor (IMU, Inertial Measurement Unit)

## II. Core Functions

It integrates a 3-axis gyroscope and a 3-axis accelerometer within a 3×3×0.75 mm LGA‑16 package, precisely detecting motion, attitude, angle and acceleration of objects.

✅ Gyroscope (angular velocity): rotation direction, tilt angle and rotation speed

✅ Accelerometer (linear acceleration): vibration, shock, collision and attitude variation

✅ Output 16-bit high-precision digital signals, communicates with MCU via I²C / SPI interface
