HMC5883L Triple Axis Magnetometer Breakout

HMC5883L is a 3-axis digital compass from Honeywell. Communication with the HMC5883L is simple and all done through an I2C interface. There is no on-board regulator, so a regulated voltage of 2.16-3.6VDC should be supplied.

This breadboard-friendly board breaks out pins  to a 4-pin 0.1" pitch header. We've also put two 10k pull-up resistors on the I2C lines.

Features:

• Simple I2C interface
• 2.16-3.6VDC supply range
• Low current draw
• 5 milli-gauss resolution

Dimensions: 

• 15.2x15.2 mm
• 0.5 gram
