3-Space Data Logger v3 BLE

The Yost Labs 3-Space Data Logger v3 BLE device merges a compact, high-precision, reliable AHRS/IMU with a micro-SD card and a rechargeable lithium-polymer battery into a single, affordable unit. It employs triaxial gyroscope, accelerometer, and magnetometer sensors, along with advanced processing and quaternion-based orientation filtering, to determine real-time orientation relative to an absolute reference. Accuracy is enhanced by gradient descent calibration and high update rates, while a dynamic sensor confidence algorithm ensures optimal precision across diverse conditions. When connected to a USB 2.0 host, it functions as both a virtual COM port and a USB mass-storage device, offering real-time sensor data, configuration options, and diagnostic tools. It provides versatile commands for raw and normalized sensor data, along with filtered absolute and relative orientation outputs in various formats. Key features include a small, self-contained design, integrated battery with extended life, wireless BLE communication, fast sensor update rates, customizable orientation sensing, advanced filtering, robust open protocol, flexible data logging, built-in clock/calendar, free firmware updates, and an RGB status LED. Recognized for excellence, Yost Labs offers custom solutions and expert support.
