Velleman VMA208 - 3-axis MMA8452Q I2C Digital Accelerometer - with connectors

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.

Name Description VCC The supply voltage - from 1,95 V to 3.6 V 3.3 V Output voltage of 3.3 V GND The ground of the system. I1 The output of the external interrupt number 1 I2 Output of external interrupt number 2 SA0 Pin of the I2C address. SCL Clock line of the I2C bus (TWI). SDA The data line of the I2C bus (TWI).

      

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.
