Quectel Expands Automotive-Grade IMU Portfolio with Three New 6-Axis Modules

Quectel Wireless Solutions announced in Munich, Germany, an expansion of its automotive-grade inertial measurement unit (IMU) portfolio. This expansion introduces three new 6-axis modules: the LUA501RA, LUA300C, and LUA301C. These modules are engineered to deliver precise motion, tilt, and orientation sensing, distinguished by automotive-grade reliability and factory calibration, which ensures a level of precision surpassing that of consumer-grade sensors.

The LUA501RA stands as the flagship module in this new release. It is a compact, high-performance 6-axis IMU developed in accordance with ISO 26262 and built around Bosch’s SMI270 chip. This module integrates a 3-axis gyroscope and a 3-axis accelerometer, making it suitable for functional-safety-critical motion-sensing applications, including those beyond the automotive sector.

Accompanying the LUA501RA, Quectel also unveiled the LUA300C and LUA301C. These are compact, automotive-grade, factory-calibrated 6-axis IMU modules based on ST’s ASM330LHB chip. While both modules share the same electrical performance and calibration methodology, they offer distinct mechanical mounting options: the LUA300C utilises pin-mounting, and the LUA301C employs screw-mounting, differing in size and weight accordingly.

Collectively, these three modules provide a diverse range of sensor platforms, footprints, and mechanical mounting options, including an ASIL-B development pedigree option. Quectel emphasizes that this expanded portfolio is designed to meet specific program, footprint, and functional-safety requirements with production-ready modules, thereby simplifying design complexity often associated with discrete sensor implementations.
