GY-271 QMC5883L/HMC5883L 3-axis Electronic Compass Module Magnetic Field Sensor

If you connect the GY-271 board and observe an I2C address of 0x0C and receive only zeros from the board, you likely have the QMC5883L chip. To work with this chip in your Arduino environment, download the appropriate library from the latest release files.

• UAVs and Robot Navigation Systems: The compact sensor fits easily into small projects, making it ideal for UAVs and robotic navigation.
• Magnetic Field Sensing: Converts any magnetic field to a differential voltage output on three axes, allowing for accurate heading calculations and magnetic field detection.

Compatibility Note:

While the HMC5883L was produced by Honeywell, its production is being phased out. The QMC5883L, made by a Chinese company with production authorization from Honeywell, shares the same hardware design but requires slightly different software due to variations in registers.

Sensor Identification:

• HMC5883L: Labeled “L883”
• QMC5883L: Labeled “5883”

• 3-Axis Magnetic Compass: Provides accurate and reliable heading information.
• Compact Design: Easily fits into small projects.
• I2C Communication: Simplifies interfacing with microcontrollers.
• Precise Heading Information: Ideal for navigation and orientation applications.

• Type: 3-axis magnetic electronic compass
• Interface: I2C
• Compatibility: Works with both HMC5883L and QMC5883L sensors (software adjustments may be needed)
