STIM210代表着全世界性能最佳的硅MEMS陀螺仪模块，对于一直迫切地想要提供更小巧、优质和便宜的解决方案的系统设计者而言，这是一项重大的突破。STIM210是一款成本和能耗低、重量轻而可靠度高的3轴陀螺仪模块。
STIM210的重量只有55克，工作温度范围内的零偏稳定性为10度/小时，零偏不稳定性为0.5度/小时。系统设计者会毫不犹豫地选择该产品来替代大且昂贵、脆弱且易磨损的现用光纤陀螺仪(FOG)和机械陀螺仪传感器。
Sensonor Technologies一直致力于拓展MEMS陀螺仪的范围并研发一整套全面的高性能惯性传感器组合，而STIM210正是公司发展过程中的又一个里程碑。
STIM210不受“国际武器贩运条例”(ITAR)限制，适用于工业、航空航天和国防市场的平台导航、导引和稳定应用。
Sensonor Technologies负责销售和营销的副总裁Hans Richard Petersen先生表示：“STIM210是我们成功之路上坚实的一步，实现了我们为市场提供更稳定、坚固和经济的高性能陀螺仪的愿景。MEMS陀螺仪的性能不断提高。在苛刻的环境中，它有更低的成本、更高的坚固性和可靠度。STIM210让我们的产品组合可以更好地应对导航和导引领域的更多应用。”
STIM210将于从6月6日开始的一周在德国Sensors and Test和美国传感器博览会(Sensors Expo)上推出。

Performance
Each axis is factory-calibrated for bias, sensitivity and compensated for temperature effects to provide high-accuracy measurements. The unit runs off a single +5V supply and communicates via a "plug & play" high-level RS422 interface. The use of a 32-bit RISC ARM microcontroller provides flexibility in the configuration, like choice of output unit, sampling frequency, LP filter -3dB frequency and RS422 bit-rate and protocol parameters.
For more advanced users, STIM210 may be put in Service Mode. In this mode all the configuration parameters can be intermediately or permanently changed by overwriting the current settings in the flash memory. Service Mode also provides the ability to perform single measurements, perform diagnostics and obtain a higher detail in the status byte.
