GY-273 3-axis Digital Magnetometer - I2C 3.3V/5V - HMC5883L / QMC5883 - Arduino

The module is based on the HMC5883L or QMC5883 IC chip enabling the measurement of the magnetic field in three XYZ axes. It communicates via the I2C interface with an accuracy of 1° to 2°. The supply voltage is 3.3 V or 5 V. The module is compatible with Arduino.

The device is available in two versions: with the HMC5883L or QMC5883 chip.

In the case of a module with the QMC5883 chip, use the Arduino library from GitHub:

https://github.com/mechasolution/Mecha_QMC5883

If the module has HMC5883L chip, download the library using the link below: Arduino HMC5883L Library

The module communicates via the I2C interface.

Pinout:

VCC - Module supply voltage in the range from 3.3 V to 5.0 V
GND - System ground.
SCL - A5 Clock line of the I2C bus (TWI), tolerates voltages d 3.3 V to 5.0 V.
SDA - A4 Data line of the I2C bus (TWI), tolerates voltages d 3.3 V to 5.0 V.
DRDY - External interrupt indicating data readiness with a low state. Default pulled up to supply voltage.
