Description

This module as Flora is composed of an accelerometer 3 axes and of a magnetometer, making it an ideal ally for a direction with precision. The accelerometer will allow you to follow the acceleration of the Earth, and the magnetometer will act as a compass to indicate your direction with respect to magnetic north. By combining these two data, you can easily guide your project.

This breakout ets module based on the famous LSM303DLHC sensor, it communicates in I2C and is very simple to use. As the circuit works in 3, 3V, elements have been added to make it compatible 5V signals, so you can utilisre in 3, 3V or 5V without problem. To use it, simply feed it man + 3 - 5V and GND pin, and read the I2C connection. There is also the DATA_READY pine and two pines of interuptons that can be used.

Each card is sold assembled and tested.
