High Accuracy 6-Axis IMU MEMS Gyroscope & Accelerometer Module for Robotics UAV
The 16488HA MEMS Inertial Measurement Unit is a high-precision six-axis sensor integrating a three-axis gyroscope and three-axis accelerometer. It delivers exceptional performance with angular rate measurement up to ±450°/s and linear acceleration up to ±20 g, featuring low zero-bias instability (0.3°/h for gyro, 0.25 mg for accelerometer) and minimal random walk (0.15°/√h for gyro, 0.029 m/s/√h for accelerometer).
This unit includes full error compensation for temperature (-45~85 °C), installation misalignment, and nonlinear corrections to ensure precise inertial data. With SPI communication at 8-15 MHz, compact size, 250 Hz bandwidth, and 0.1% cross-coupling, it's ideal for UAV navigation, autonomous vehicles, robotics, industrial automation, marine/aerial navigation, mapping, satellite attitude control, and defense guidance systems.
