Review: Beware magnetic header pins - As many others have noted, this board is based on a QMC5883L (I2C address 0x0D) and not a HMC5883L as the chip itself is labeled. I have successfully used it with the QMC5883LCompass library for ESP32 and it works just fine except for calibration problems. Thanks to another reviewer I found that the header pins that the vendor supplied with the module have iron in them and so are distorting the readings to such an extent that the calibration routine supplied with the Compass library cannot fully compensate. As a result I cannot get an azimuth reading in the range of 0 to 359. I will have to replace the header pins with some I have tested with a magnet to ensure they do not have any iron in them, and then rerun the calibration test to get the calibration parameters for my sketch. This whole challenge could easily have been mitigated if the vendor had bothered to do a simple magnetic test on the shipped header pins. This is extraordinarily poor QA, considering that this module is iron sensitive by its very nature since it is a magnetometer. The vendor should include a warning in their listing to check that any pins used are not magnetic before soldering them onto the board. That would have helped me a lot. Giving us non-magnetic pins would be even better, vendor take note! All that said, these seem to be perfectly good QMC5883L modules. I just recommend testing the header pins with a kitchen magnet before soldering them to the board. If you're like me you probably have a junk box lying around with other header pins that you could substitute if the delivered ones prove to be magnetic. Review: Not HMC part - As of December 2022 they are shipping QMC5883 units. Easy to tell ... just run the i2C scanner. If you see 0x0D it's a QMC, a 0x1E it's a HMC part. That said, I proceeded to test it out. Worked ok and is pretty stable, needing less filtering than a AK8975. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0855TZV1J | | Best Sellers Rank | #110,756 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #45 in Science Education Magnets & Magnetism Kits | | Brand | Comimark | | Centerline Length | 1.85 Centimeters | | Connector Type | Screw | | Date First Available | February 26, 2020 | | Item Weight | 0.634 ounces | | Item model number | GY-273 | | Manufacturer | Comimark | | Material | Polymer | | Mounting Type | PCB Mount | | Number Of Contacts | 1 | | Number Of Poles | 2 | | Package Dimensions | 4.69 x 3.03 x 0.55 inches | | Specification Met | CE, FCC | | UPC | 657835733490 | | Upper Temperature Rating | 85 Degrees Celsius | ## Product Details - **Brand:** Comimark - **Centerline Length:** 1.85 Centimeters - **Connector Type:** Screw - **Manufacturer:** Comimark - **Material:** Polymer - **Mounting Type:** PCB Mount - **Number Of Contacts:** 1 - **Number Of Poles:** 2 - **Specification Met:** CE, FCC - **Upper Temperature Rating:** 85 Degrees Celsius ## Images ![2Pcs GY-273 HMC5883L 3V-5V Triple Axis Compass Magnetometer Sensor Module for Arduino - Image 1](https://m.media-amazon.com/images/I/519iJLCPm2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Beware magnetic header pins *by M***N on October 19, 2025* As many others have noted, this board is based on a QMC5883L (I2C address 0x0D) and not a HMC5883L as the chip itself is labeled.
