Honeywell recommends that customers begin by evaluating the HMC5883L using the demonstration board with a USB interface and computer software. The HMC5883L-demo provides a user friendly method of viewing compass heading, pitch and roll data both numerically and on aviation-type displays. Communication can still be enabled with the HMC5883L, even without the provided demonstration software, as long as the developer creates a program to emulate the I²C data packets. Additionally, Honeywell offers an HMC5883L evaluation board for the compass IC which contains the HMC5883L atop a 0.8 x 0.8 inch plug-board with wide-DIP spaced 0.6" pins for solderless breadboard compatibility. This evaluation board also contains the two capacitors and I²C pull-up resistors needed for the retrieval of the XYZ magnetic field information. Both single and dual supply configurations of the HMC5883L are supported.
