The BMM150 is a low-power, low-noise 3-axis digital geomagnetic sensor from Bosch Sensortec. It is designed for use in compass applications, and is especially suited for supporting drones in accurate heading.

The BMM150 is based on Bosch's proprietary FlipCoreTM technology, which provides high accuracy and dynamics. It is also very small and lightweight, with a footprint of only 1.56 x 1.56 mm² and a height of 0.60 mm. This makes it ideal for use in mobile devices and other space-constrained applications.

The BMM150 has a number of features that make it well-suited for compass applications. It has a wide operating range of -40°C to +85°C, and can measure magnetic fields of up to 1.3 Gauss. It also has a low power consumption, making it ideal for battery-powered devices.

The BMM150 can be used with an inertial measurement unit (IMU) consisting of a 3-axis accelerometer and a 3-axis gyroscope to provide absolute spatial orientation and motion vectors with high accuracy and dynamics. This makes it ideal for use in drones, robots, and other applications where precise navigation is required.

Here are some of the key features and benefits of the BMM150:

Low power consumption Low noise High accuracy and dynamics Wide operating range Small size and lightweight Easy to use The BMM150 is a versatile sensor that can be used in a wide range of applications, including:
