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. On the board are two chips: 3-axis gyroscope and 3-axis accelerometer. Sensors of this type are used in smartphones, tablets, as well as in various controllers of video games.
To communicate with the central unit, the user can select the SPI interface or I2C interface (in standard mode, up to 100 kHz and fast up to 400 kHz). 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 of the sensors can be found inthe documentation.
Since the maximum voltage, with which the system works, is 3.3 V, to work with Arduinonecessary 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.
