GY-271 HMC5883L 3-Axis Magnetic Electronic Compass Module
Introduction
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. |
