Mikroe Compass 4 Click measures the three-axis magnetic field for implementation in electric compasses applications. The board features the AKM AK09915 3-axis magnetic sensor with signal processing. The devices use the I2C or SPI protocol for obtaining sensor measurement data of the magnetic field. The sensor has the capability to measure magnetic fields within the full-scale range of ±4912μT, with a sensitivity of 0.15µT per LSB, resolution at 16bits, and built-in Noise Suppression Filter (NSF).
