Sensor for measuring the acceleration in three axes in the range of +/- 16 g. The module is powered with the voltage from 3 to 5 V, it has the voltage regulator, communicates via the I2C bus (TWI) or SPI.
The module has necessary for the correct operation of the system, passive elements. Pins are popular goldpin connectors for connecting the sensor via wires or to directly attach the breadboard.
The product is compatible with Arduino
Library and connection diagram with Arduino, you can find it at this address.
The system can be combined with the central unit via the bus I2C or SPI. To select I2C, you should indicate logical unit to CS pin or to pernamently pull CS at a constant voltage. The I2C address depends on the state at pin SDO. In the case of high status, it has a value of: 0x1D, at low status: 0x53. Details, in documentation and tutorial.
The sensor has eight pins for the installation of connectors of goldpin type - pitch of 2.54 mm (included).
