6DOF 3-Axis Digital Compass - Super High Precision by GY-511


The LSM303DLHC is a digital 3 axis accelerometer and 3 axis magnetometer with I2C interface. It has full-scale acceleration range of ±2g to ±16g and full scale magnetic field range of ±1.3 to ±8.1 gauss. All the full scale ranges are user selectable.

Module has on board low drop voltage regulator which takes input supply in the range of 3.6V to 6V DC. Board has two mounting holes. All 9 pins of the module are arranged in single line. LSM303DLHCs I2C serial bus interface supports standard (100 KHz) and fast mode (400 kHz).

It is most suitable for tilt compensated compass, quadrotor and robotics application. For LSM303DLHC application interface example available based on LPC2148 ARM7 microcontroller. LSM303DLHC has application example based on LPC2148 ARM7 microcontroller.
