The SparkFun Micro 6DoF IMU Breakout features the STMicroelectronics LSM6DSV16X — a high-performance, low-power 6-axis IMU with a 3-axis accelerometer and 3-axis gyroscope. Its triple-core architecture processes data on three separate channels (UI, OIS, EIS) with dedicated configuration, processing, and filtering. All in a tiny 0.75 × 0.30″ Qwiic Micro footprint.

The LSM6DSV16X includes a programmable finite state machine (FSM) for configurable motion tracking and a machine learning core (MLC) for AI-powered contextual awareness. Embedded Qvar electrostatic sensing enables touch-style interactions like tap, double tap, long press, and swipe gestures.
