Introduction

GY-271 HMC5883L 1.jpg
The Compass Module is designed for low-field magnetic sensing with a digital interface and perfect to give precise heading information. This compact sensor fits into small projects such as UAVs and robot navigation systems. The sensor converts any magnetic field to a differential voltage output on 3 axes. This voltage shift is the raw digital output value, which can then be used to calculate headings or sense magnetic fields coming from different directions.

Introduction of Pins

Pin Introduction
VCC Connected to the anode of the power supply (3~5v)
GND Connected to the cathode of the power supply
SCL I²C clock
SDA I²C data
DRDY Interrupting pin for data preparation, DRDY is pulled up inside and keeps the low level for 250μsec when the data are on the output register.
