7Semi BMM350 Triple Axis Magnetometer Sensor Breakout for AR and VR – High Precision Geomagnetic Sensing with Low Power Operation

The 7Semi BMM350 Triple Axis Magnetometer Sensor Breakout is a precision geomagnetic sensor designed for advanced spatial orientation, motion tracking, and navigation tasks. Built on Bosch’s next-generation TMR (Tunnel Magnetoresistance) technology, it delivers ultra-low noise, high accuracy, and long-term stability for applications requiring exact directional data. Its Field Shock Recovery mechanism ensures consistent performance even in environments with strong or fluctuating magnetic fields, making it ideal for AR, VR, and robotics systems.

With support for both I2C and I3C interfaces, the BMM350 simplifies system integration and data transfer in compact designs. It maintains compatibility with the earlier BMM150 series, offering improved precision, higher sampling rates, and greater energy efficiency. This breakout board is a perfect fit for battery-powered devices, head tracking systems, and sensor fusion platforms requiring reliable 3-axis magnetic field data.
