This is a breakout board for Honeywell's HMC5883L, a 3-axis digital compass, provides compass heading accuracy up to 1° to 2°. Communication with the HMC5883L is simple and all done through an I2C interface. An Arduino Demo is given out to help users learn how to use this sensor.

The breakout board includes the HMC5883L sensor and all filtering capacitors as shown. This module also includes a DC regular for power supply requirement. Hence user can connect any 3.3V to 6V DC power supply.
