3-Space TSS-Nano All-in-one AHRS/IMU IC
Description
The Yost Labs 3-Space Sensor™ Nano is an super-miniature, all-in-one IC / AHRS with high-precision, high-reliability, low-cost, and extremely low power consumption. The Nano is an SMT Attitude and Heading Reference System (AHRS) / Inertial Measurement Unit (IMU) which uses triaxial gyroscope, accelerometer, and compass sensors in conjunction with advanced processing and on-board quaternion-based orientation filtering algorithms to determine orientation relative to an absolute reference in real-time. Delay 5ms時延5毫秒.
The 3-Space Sensor™ Nano is pre-programmed IC / AHRS chipset with our QGRAD2™ filter that can be installed into the likes of any product. However the Nano is available as a pre-packaged carrier / development sensor, or can be purchased individually as the IC / AHRS chipset. We also offer fully featured Evaluation Kits designed for the Nano which can be used for testing and external development.
