Description
Description Unit BMM350 is a three-axis magnetometer unit featuring the BMM350 sensor and supporting 100 kHz and 400 kHz communication rates. Based on TMR (tunnel magnetoresistance) technology, it measures magnetic fields along the X/Y/Z axes with approximately 0.1 μT resolution and excellent temperature stability. The module transmits data over I2C, provides real-time three-axis geomagnetic data, and supports heading detection after calibration, making it suitable for robot navigation, heading detection, electronic compass, motion tracking, and magnetic field sensing. Features BMM350 three-axis TMR magnetometer Measurement axes: X / Y / Z Magnetic field resolution: approx. 0.1 μT Magnetic field range: ±2000 μT (typical) Magnetic sensing technology: TMR (tunnel magnetoresistance) Communication rate: 100 kHz / 400 kHz Supports heading readout and calibration Includes 1 x Unit BMM350 1 x HY2.0-4P Grove Cable (5cm) Applications Robot navigation Heading detection Electronic compass Motion tracking Magnetic field sensing Specifications Specification Parameter IC Model BMM350 Sensor Type Three-axis magnetometer Magnetic Field Range X/Y/Z axes: ±2000 μT (typical on each axis) Magnetic Field Resolution approx. 0.1 μT Communication Interface I2C @ 0x14 I2C Communication Rate 100 kHz / 400 kHz Sleep Current 6.42 μA (measured) Continuous Read Current 167.02 μA (measured) Heading Accuracy Error < 10° after calibration Operating Temperature Range -40 ~ 85°C (chip specification) Product Size 24.0 x 24.0 x 8.0mm Product Weight 3.1g Package Size 138.0 x 93.0 x 7.0mm Gross Weight 6.6g Product Comparison Product Comparison Unit DoF6 Unit DoF9 Unit DoF10 Unit BMM350 Sensor Combination BMI270 BMI270 + BMM350 BMI270 + BMM350 + SPA06-003 BMM350 Sensor Type Six-axis inertial sensor Six-axis inertial + three-axis geomagnetic sensor Six-axis inertial + three-axis geomagnetic + barometric pressure sensor Three-axis geomagnetic sensor Accelerometer 16-bit 3-axis 16-bit 3-axis 16-bit 3-axis ❌
