Wit Motion WT61 6-Axis IMU Attitude Measurement Module
Vendor: 维特智能 Wit Motion (中国深圳)
Product: WT61 六轴 IMU 姿态测量模块
Wit Motion (Shenzhen) WT61 is a cost-effective 3-D attitude measurement system based on MEMS technology, integrating a 3-axis gyroscope and 3-axis accelerometer. Its proprietary Kalman-filter sensor-fusion algorithm outputs temperature-compensated 3-axis attitude angles at up to 100 Hz in real time. Accelerometer ±16 g range with 0.0005 g/LSB resolution and 0.75~1 mg RMS noise at 100 Hz bandwidth; gyro ±2000 °/s with 0.05 °/s RMS noise; 0.2° roll/pitch accuracy and 0.5° static heading accuracy (6-axis algorithm). The module ships with a metal shield case for good EMI immunity and easy mounting, making it one of the most popular entry-level IMUs for humanoid robots, robot dogs, AGVs, gimbals and education.
