MG-502

The MG-502 high-performance single-axis MEMS gyroscope features a maximum 12kHz data rate, adjustable bandwidth, and 24-bit output accuracy, making it an ideal choice for drone gimbal stabilization, attitude control, and inertial navigation systems.   In modern drone systems, flight attitude stability is a prerequisite for safe operation and mission execution. Whether facing turbulent airflow, sudden load changes, or aggressive maneuvers, the aircraft is constantly subjected to angular motions—pitch, roll, and yaw. Capturing and reacting to these dynamic changes demands a precise, high-speed sensor. This is where MEMS gyroscopes like the MG-502 step in as the silent but essential “sensory organ” of drones. Precision in a Single Axis: The Power of MG-502 Unlike traditional three-axis solutions, the MG-502 focuses on extreme precision along a single axis, making it ideal for integration into gimbals, stabilization platforms, and INS subsystems requiring highly accurate feedback in one rotational direction. Key features include: High-speed angular rate capture: With data output rates configurable up to 12,000 Hz, the MG-502 enables ultra-fast response to angular changes, making it capable of tracking rapid drone maneuvers without delay. 24-bit angular velocity output resolution: Combined with factory-calibrated scale factors, this ensures high-fidelity angular velocity data for flight control algorithms. Adjustable output bandwidth from 12.5 Hz to 800 Hz: This allows developers to fine-tune noise suppression and dynamic response depending on the application—be it smooth cinematic capture or agile flight stabilization. SPI interface with precise timing: MG-502 supports SPI Mode 3 communication, allowing reliable real-time integration with flight control units. Built for Real-World Integration The MG-502 isn't just about internal specs—it’s built with system-level integration in mind: Compact 48-pin ceramic package: Easily mounted on PCBs with minimized signal interference, the sensor supports robust layout for anti-vibration and EMI-sensitive designs. Power-efficient operation: With a 5V input and average current of ~35mA, it matches well with UAV power budgets, including those of long-endurance drones. Configurable sync options: Developers can choose between internal timing or external synchronization signals to align data output with system-wide sensor fusion cycles—ideal for time-critical navigation applications. Applications: Stability Engineered for Critical Tasks Drones equipped with the MG-502 gain a significant edge in: Gimbal stabilizationReal-time angular velocity output helps drive precise counter-rotation in brushless motors, effectively cancelling platform vibration and improving image clarity. Inertial navigation backupWhen GPS signal fails, the MG-502’s high data fidelity feeds into strapdown INS algorithms, aiding short-term dead reckoning navigation. Flight attitude loopIntegrated into the main flight controller, the MG-502 provides essential feedback for PID controllers to maintain roll/pitch/yaw stability under unpredictable conditions. Final Thoughts While three-axis MEMS gyros dominate the headlines, sometimes one axis is all you need—if it’s precise enough. The MG-502 high-precision single-axis MEMS gyroscope brings together ultra-fast data response, configurable bandwidth, and industrial-grade reliability. It is the perfect choice for drone engineers seeking ultimate control fidelity along a critical axis.   In the fight against gravity and chaos, the MG-502 doesn’t just measure rotation—it defines stability.
