Description

The MEMS module allows you to measure acceleration, magnetic field and angular velocity in three-dimensional space. Using this data, the user can identify the device in three-dimensional space. Sensors of this type are used in smartphones, tablets, as well as in various controllers of video games.

 

 

The I2C interface is to communicate with the central unit. The module has necessary for the correct operation of the system, passive elements. Pins are the holes for soldering of the goldpin connectors (not included) which enables the connection of the sensor via wires or a direct atachment to the breadboard.

Details concerning the technical parameters can be found in the documentation.

 

Since the maximum voltage, with which the system works, is 3.3 V, to work with Arduino needed is a voltage converter. The exceptions are the modules operating with voltages of 3.3 V, for example, Arduino Pro Mini 328 - 3.3 V/8 MHz.

 

The product is compatible with Arduino

To facilitate the use of this module, a manufacturer prepared a user manual along with a sample program for the Arduino and design files with a library, available on the GitHub.

 

Pins

The sensor has pins for mounting goldpin connectors - the pitch of 2.54 mm (not supplied, must be purchased separately and self-soldered).
