The Yost Labs 3-Space Sensor™ LX is an ultra-miniature, high-precision, high-reliability, low-cost 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.

Includes: 1 x LX Embedded Sensor + 1 x LX Embedded Evaluation Kit  

Key Features

The Yost Labs 3-Space Sensor™ LX is a highly flexible, low-cost, high-performance AHRS / IMU package that is perfect for a wide variety of projects requiring a reliable orientation sensing solution.

  • Ultra-small high-performance AHRS at 16mm x 15mm x 1.7mm and 0.9 grams
  • Open Source API Available
  • Fast sensor update and filter rate allow use in real-time applications, including stabilization, virtual reality, pedestrian tracking, real-time immersive simulation, and robotics
  • Advanced on-board magnetometer auto-calibration allows the sensor to quickly adapt to changing magnetic environments.
  • Highly customizable orientation sensing with options such as tunable filtering, oversampling, and orientation error correction
  • Advanced integrated QGRAD2TM filtering allows sensor orientation outputs at up to 1750Hz while automatically reducing the effects of sensor noise and sensor error
  • Robust open protocol allows commands to be sent in human readable form, or more quickly in machine readable form
  • Orientation output format available in absolute or relative terms in multiple formats (quaternion, rotation matrix, axis angle, two-vector)
  • Absolute or custom reference axes
  • Access to raw sensor data
  • Embedded pedestrian tracking
  • Flexible communication options: SPI, I2C, USB 2.0, or asynchronous serial USB communication through a virtual COM port
  • Castellated SMT edge pads provide secure SMT mounting and allow optional through-hole mounting
  • Upgradeable firmware
  • Programmable interrupt capability
  • Development kit available
