The sensor is used to determine the acceleration and magnetic field. The measurement of these quantities is made possible by a 3-axis accelerometer and magnetometer and the passive elements necessary for the correct operation of the system. The integrated regulator allows powering the module with any voltage from 2.5V to 5.5V.
For communication with the central unit, the popular I2C bus (TWI) is used. The outputs are the popular goldpin connectors, which enable the sensor to be connected by wires or directly connectedtothe contactplate. The manufacturer has prepareda libraryfor easy operation of Arduino sets.
The sensor has nine leads for mounting goldpin-type connectors - 2.54mm raster (included). On customer's request we can solder the strip.
