Confirm configuration, interfaces and documentation with your inquiry.

The JDWZZ3430B is a high-precision 9-DOF MEMS inertial measurement unit integrating three complementary sensor systems. The gyroscope provides ±100°/s measurement range with exceptional zero bias stability (≤0.1°/h), the accelerometer offers ±10g range with superior stability (≤50μg), and the magnetic sensor features ±8G range with high resolution (3000LSB/G). All three sensing systems are supported by comprehensive signal processing capabilities and operate at up to 1000Hz sampling rate, with the magnetic sensor data available at up to 200Hz. This integration enables high-precision motion and orientation measurement across nine degrees of freedom.
