The LSM303 breakout board combines a magnetometer/compass module with a triple-axis accelerometer to make a compact navigation subsystem. The I2C interface is compatible with both 3.3v and 5v processors and the two pins can be shared by other I2C devices. Combined with a 3-axis gyro such as the L3GD20, you have all the sensors you need for a complete IMU (Inertial Measurement Unit) for use in aerial, terrestrial or marine navigation.
In this tutorial we will show you how to connect the LSM303 to an Arduino and use it to measure orientation relative to the earth’s magnetic field, and acceleration in three axis.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
