Description

KAmodLSM303 is a module with MEMS LSM303D type. Chip has a digital output (with using I2C or SPI interface) and allow to make a measurement of acceleration and magnetic field value in three axis. Thanks to programmable interrupt outputs, it is possible e.g. wake up a microcontroller after free fall detection or object movement. Module can be used in system with power supply 2.5 - 5.5V.
