LSM303D is a system in package featuring a 3D magnetometer and a 3D high resolution accelerometer.

It is the latest generation of E-compass from STMicroelectronics with high flexibility, high stability over temperature for a consumption of only 300 uA in normal mode and 1 uA in power-down mode (Accelerometer and Magnetometer).

Interrupt generators can be configured by the user for free-fall, motion detection and magnetic field detection.

It is available in a LGA-16 package 3 x 3 x 1 mm³.

LSM303D has the same footprint as the 3x3 accelerometer standalone (LIS3DH and LIS3DSH).
