Product Description

MEMS 3-Axis Angular Rate Sensor with SPI Digital Output Stim210 Replacement

The MG3-1A MEMS Gyroscope is a high-precision 3-axis angular rate sensor designed for inertial navigation systems, UAVs, robotics, and autonomous platforms. The device integrates a 3-axis MEMS gyroscope, temperature sensor, signal processing board, structural components, and dedicated software, providing real-time compensated angular rate measurements via an RS-422 serial interface.

With a measuring range of ±400°/s, low zero-bias instability (0.3 °/h), and minimal random walk (0.15°/√h), it ensures high-precision motion sensing. The MG3-1A supports temperature compensation, installation misalignment correction, and nonlinear compensation, making it ideal for UAV navigation, robotic stabilization, attitude measurement, and autonomous motion control.

Fully compatible with Stim210, it serves as a drop-in replacement for precision gyroscope applications, providing robust performance under extreme temperatures (-45~85 °C) and harsh environmental conditions.
