## Description

BMM150 is a low-power and low-noise 3-axis geomagnetic sensor from Bosch for compass applications. It allows measurements of the magnetic field and compass angle in three perpendiculars within a measuring range of ±1300uT on X and Y axis and ±2500uT on Z axis.Featuring small size and lightweight, the sensor has a 2-bit DIP switch for I2C address setup, and 4 addresses are available. Based on Bosch's proprietary FlipCore technology, the performance and features of BMM150 are carefully tuned and thus can offer absolute spatial orientation without calibration, perfectly matching the requirements of all 3-axis mobile applications such as robot navigation & positioning, electric compass, electric map, navigation or augmented reality.Connection Diagram with FireBeetle 2 ESP32-E IoT MicrocontrollerFeaturesProgrammable interrupt pinConfigurable four I2C addressesLow noise(0.3-1.4uT)High accuracy(30μT horizontal geomagnetic field component, ±2.5°)ApplicationsDronesCompassIndoor/Outdoor NavigationHead Motion TrackingAugmented RealityTilt-compensated Electric MapSpecificationPower Supply: 3.3V-5VOperating Temperature: -40 to 85°CCommunication: I2CResolution: 0.3μTZero Offset: ±40μT/±2μT (software optimized)Non-linearity: <1%FS Measuring Range: ±1300μT (x & y axis), ±2500μT (z-axis)Operating Current: 1.7mA@ frequency 10HzLow Noise: 0.3-1.4μTAccuracy: 30μT horizontal geomagnetic field component, ±2.5°Start-up Time: 3msDocumentsProduct wikiSTP 3D Model2D CAD DimensionsSchematicsDatasheetShipping ListGravity: BMM150 Triple Axis Magnetometer Sensor ×1Gravity-4P I2C/UART Sensor Cable ×1Black Single-row Pin Header-5PIN ×1
