2 pièces GY-273 HMC5883L Triple axe boussole Magnétomètre Module capteur 3V-5V

The three-axis digital output magnetoresistive sensor for digital compasses is currently the most suitable small, calibration-free, low-power, and low-cost electronic compass for mobile phones and other portable devices on the market.

The small board integrates all the resistors and capacitors required by the HMC5883L and only needs an external power supply and GND, SDA, and SCL lines to read data via the IIC interface.

Supply voltage: 3.3V or 5V; Digital output: 2C digital output interface, designed for ease of use; High accuracy: 1-2 degrees, integrated 12-bit A/D converter, OFFSET circuit, SET/RESET, no magnetic saturation, no cumulative error;

Low power consumption: 1.8V supply voltage, standby power consumption -2.5 μA, measurement mode -0.1 mA. It supports automatic calibration procedures, simplifying usage steps, and the final product is very convenient to use; the integrated self-test circuit facilitates mass production testing without adding expensive extra testing equipment. Primarily used in smartphones, sports watches, portable compasses, automotive electronics, etc.
