Micro-Magic Inc. has introduced the U4930 series, a high-precision MEMS inertial measurement module designed to serve as a compatible upgrade path for Honeywell‘s HG4930 IMU.
The launch targets integrators in high-stakes sectors including industrial drones, autonomous driving, mobile surveying, and high-precision navigation. By maintaining a physical form and electrical interface similar to the HG4930, the U4930 allows for seamless adaptation into existing system spaces and power architectures. The module measures 64.8 x 47 x 35.3 millimeters, weighs approximately 130 grams, and operates with a steady-state power consumption of less than 2 watts, effectively reducing mechanical and electrical redesign costs for users during hardware transitions.
Technical specifications for the U4930 indicate comprehensive performance improvements over its benchmarks. The unit integrates high-performance three-axis MEMS gyroscopes and accelerometers, utilizing internal algorithms for precise compensation across the entire operating temperature range. The gyroscope measurement range reaches up to ±500°/s, while the accelerometer range reaches ±30g. Key precision metrics include a gyro bias stability of 0.3°/h and an angular random walk as low as 0.02°/√h, meeting the rigorous demands of sophisticated attitude measurement applications.
To ensure reliability in high-dynamic and harsh environments, the module features a data output rate of up to 2000Hz and includes specialized anti-vibration and anti-impact designs. System integration logic remains consistent with industry standards through an RS422 differential communication interface. The module supports custom communication protocols and provides synchronization for GPS/GNSS time data and Pulse Per Second (PPS) signals.
Micro-Magic stated that the product is designed to be “compatible with HG4930”, providing a practical and feasible technical path for existing HG4930 users seeking supply chain diversification, cost optimization, or performance improvement.
The U4930 series is available in three distinct precision levels, models A, B, and C, to accommodate requirements ranging from industrial applications to cutting-edge scientific research. This launch signals an increasing capability to benchmark directly against international mainstream products in the high-precision MEMS inertial measurement field, offering engineers more flexible solution choices through intentional compatibility design.
