Magnetometer for 3D VR/AR indoor navigation and more

Mouser now offers the BMM350 high-performance magnetometer from Bosch. This High-Performance Magnetometer is an ultra-small, high-performance, low-current, 16-bit three-axis magnetometer, ideal for a wide range of consumer applications such as virtual, augmented, and mixed reality applications, head orientation, indoor navigation, magnetic compass, high-end gaming and robotics.

The high-performance magnetometer is based on Bosch's proprietary TMR technology with field shock recovery features that offer protection against external magnetic fields while ensuring high accuracy. For AR/VR, ultra-precise digital pathfinding enhances tracking of head movements and 3D audio, decreasing pixel latency and motion sickness for VR users. New data-ready interrupt signals and data-ready status register read-outs provide the device with instant data updates and status polling of positioning and speed detection for indoor navigation and AR/VR applications.

The device permits measurements of the magnetic field in three perpendicular axes, with a magnetic field range of typical ±2000µT (x, y, z-axis) and a low current consumption of ±200µA @ 100Hz in low power preset. The device is ideal for many target orientation applications, with a low noise ratio of ±190n Trms for x, y-axis and ±450n Trms in z-axis.

The sensor module is housed in a compact nine-pin WLCSP with a footprint of only 1.28mm × 1.28mm and a sensor height of 0.5mm. The sensor's small dimensions and low power consumption make it excellent for use in portable and battery-driven applications.
