The LSM9DS1 sensor, used on our ELEV-8 v3 Quadcopter s Flight Controller, is now available in a SIP module for easy prototyping or conveniently studying the physics involved in motion tracking. This LSM9DS1 sensor is a system-on-a-chip that takes 4 kinds of measurements, using: a 3-axis accelerometer (for measuring gravity or acceleration in 3D space), a 3-axis gyroscope (for measuring rotation), a 3-axis magnetometer (for measuring magnetic field strength - used to find Magnetic North), and a temperature sensor. The LSM9DS1 9-axis motion sensor module can be used with nearly any microcontroller. It can be powered by 2.8, 3.3 or 5 volts and it uses either a 3-pin SPI interface or an I2C bus. Use it as a single sensoraccelerometer, a gyroscope, a magnetometer, or a temperature sensoror all of the measurements can be read together for use in inertial measurement or dead-reckoning applications. It can also be configured to drive an interrupt when detecting impacts, free-fall, or magnetic field ranges. Features Measures linear acceleration, angular velocity, and magnetic field strength on three axes Measures the temperature, and internally temperature compensates all readings Low power usagegreat for battery-powered applications 16-bit precision with selectable sensitivity, adaptable to many project s needs Breadboard friendly SIP form-factor Copyright Parallax Inc.

This module has a linear acceleration full scale of 2g/4g/8/16 g, a magnetic field full scale of 4/8/12/16 gauss and an angular rate of 245/500/2000 dps. The LSM9DS1 includes an SPI serial standard interface. Magnetic, accelerometer and gyroscope sensing can be enabled or set in power-down mode separately for smart power management. The logic level shifters ensure that the I/O connections operate at the same voltage supplied to the VIN pin. This means the module is compatible with 2.8V, 3.3V, and 5V microcontrollers.
