GY-271 HMC5883L Electronic Compass Triple Axis Magnetometer Sensor is a 3-axis digital compass used for two general purposes: to measure the magnetization of a magnetic material like a ferromagnet or to measure the strength and, in some cases, the direction of the magnetic field at a point in space. Communication with the HMC5883L is simple and all done through an I2C interface. There is an onboard regulator. The breakout board includes the HMC5883L sensor and all filtering capacitors. The power and 2-wire interface pins are all broken out to a 0.1″ pitch header. Uses the famous HMC5883L magnetometer chip. Supports 3.0V to 5.0V IO levels on I2C SCL and SDA pins.

Notes:

1. There may be slight size deviations due to manual measurement, different measuring methods and tools.
2. The picture may not reflect the actual colour of the item because of different photographing light, angle and display monitor.
