GY-273 QMC5883L 3-Axis Compass Magnetometer Module

The 3-axis compass module GY-273 is suitable for navigating robots and drones or for building a digital compass. Communication runs over the I2C bus. Depending on the delivery, this type of module carries different chips that differ in address and library. The marking on the board says nothing about this, an I2C scanner shows the chip.

Recommended alternative with a clearly named chip: Gravity BMM350 3-Axis Magnetometer Sensor for AR/VR

Recommended Accessories:

• Dupont Cable M-F 20cm 20 Pieces

Features:

• Address 0x0D: QMC5883L, library QMC5883LCompass
• Address 0x1E: HMC5883L, library Adafruit HMC5883 Unified
• Address 0x2C: QMC5883P, library Adafruit QMC5883P
• The chips are not compatible with each other, each needs its own library
