Overview
The LSM6DSL Click Board™ measures linear and angular velocity with six degrees of freedom. It carries the LSM6DSL high-performance 3-axis digital accelerometer and 3-axis digital gyroscope. The Click Board™ is designed to run on a 3.3V power supply.
The LSM6DSL Click Board™ communicates with the target microcontroller over SPI or I2C interface, with additional functionality provided by the INT pin on the MikroBUS line.

Mode 1: I2C slave interface or SPI serial interface is available.
Mode 2: I2C slave interface, or SPI serial interface and I2C interface master for external sensor connections, are available.
LSM6DSL INERTIAL MODULE FEATURES
The LSM6DSL is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope performing at 0.65 mA in high-performance mode and enabling always-on low-power features for an optimal motion experience.
The event-detection interrupts enable efficient and reliable motion tracking and contextual awareness, implementing hardware recognition of free-fall events, 6D orientation, click and double-click sensing, activity or inactivity, and wakeup events
The LSM6DSL has a full-scale acceleration range of ±2/±4/±8/±16 g and an angular rate range of ±125/±245/±500/±1000/±2000 dps (degrees per second).
