Description
Sensor for measuring acceleration in three axes. It is characterized by small size, low energy consumption and simple usage. It communicates via the I2C bus.
|
The module has soldered pins in the form of goldpin strap. |
Communiaction
For communication with the central unit, it uses the popular I2C bus (TWI). The module has necessary for the correct operation of the system, passive elements. Pins are the popular goldpin connectors, for connecting the sensor viawiresor the direct attachment to the breadboard.

The product is compatible with Arduino Online, you can findthe sample programfor users ofArduino. |
The maximum voltage, with which the system works, is 3.6 V, so to work with theArduino, required 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.
