DescriptionThe "GY-271 HMC5883L" is a specific module that incorporates the HMC5883L magnetometer sensor. It is commonly used in electronic projects to measure and detect magnetic fields.
Here's what the description means:GY-271: "GY-271" is the model number or identifier of the specific breakout board or module that houses the HMC5883L sensor. It's common for sensor modules to have different breakout boards with specific names or numbers, making it easier to identify and use in projects.
HMC5883L: The "HMC5883L" is the actual magnetometer sensor chip used in the module. It is manufactured by Honeywell and is known for its high accuracy in measuring magnetic fields.
Magnetometer Sensor: A magnetometer is a type of sensor that is capable of detecting and measuring magnetic fields. The HMC5883L is a three-axis magnetometer, meaning it can measure magnetic fields in three dimensions: X, Y, and Z. This capability allows it to determine both the strength and direction of magnetic fields.
The GY-271 HMC5883L module is widely used in various applications, such as compass modules, heading determination in robotics and drones, navigation systems, geomagnetic field measurement, and more. When connected to a microcontroller or development board (e.g., Arduino), the sensor can provide precise magnetic field data, which can then be used for orientation or navigation purposes in your projects.
To use the GY-271 HMC5883L effectively, you'll need to interface it with a microcontroller and communicate with it using the I2C (Inter-Integrated Circuit) protocol.
Applications:Navigation and Orientation: One of the primary applications of the HMC5883L module is navigation systems. It can be used to determine the direction an object is facing relative to the Earth's magnetic north. This can be particularly useful in applications like robotics, drones, and autonomous vehicles.
Digital Compass: The module can serve as a digital compass in various devices, providing users with real-time information about their orientation. This is useful in applications such as smartphones, tablets, and GPS navigation devices.
Geocaching: Geocaching enthusiasts use electronic compass modules to help them find hidden caches by providing accurate directional information.

Initially couldn't get flight controller to reliably communicate with this module, but then I popped off the 2 pull-up resistors (the absolutely TINY things right next to the SDA and SCL pads on the board) to ensure it would work with other devices connected to the bus, and from then on there have been no issues at all.
Works as expected. Side story: Don't drop it. It breaks easily. My group partner and I were outside soldering jumper wires to this chip. Music was playing outside because there was a band concert at my University. If only I could attend the Spring Show. But I had to focus on my project. So we finished soldering. Then we walked back to the lab with our hands full. I tried opening the door and this chip fell. The music played on. People were cheering. I looked at the chip in shock. It was broken. I had to purchase a second one. I know it's common sense not to drop sensitive things like this. I just wanted to give you a story.
I needed a position sensor for my attic antenna and this worked perfectly. The QMC is supposed to be inferior to the HMC; however, it is more than adequate for my purposes! I.e., it is quite accurate in provided 360 degree precision, although in my application, it seems to have a margin of error of 2 degrees, which is still overkill for me.
Works as expected.
Worked well. A little difficult to mount with no mounting holes. Not plug and play.
There is a lib in Arduino for the QMC5883L and it does work well.
Set this up with an arduino uno and integrated it into a ROS system. Put it on a chip socket that is permanently mounted onto a proto shield.
