Fermion: BMM350 Triple Axis Magnetometer Sensor
Overview
The SEN0622 is a compact magnetometer breakout board based on the Bosch BMM350, designed for the Fermion platform. This high-performance 3-axis geomagnetic sensor provides precise magnetic field measurement for orientation and navigation tasks in space-constrained designs. It consumes only 0.2mA in normal mode at a 100Hz sample rate, making it suitable for battery-powered applications.
Why Choose This Part
The BMM350 offers a wide measurement range of +/- 2000 uT on all three axes and an operating temperature range from -40C to +85C. It features a high resolution with a typical accuracy of 1.3 percent and communicates over a standard I2C interface. The Fermion platform footprint ensures easy integration into breadboards and prototyping systems.
Applications
Key Specifications
Getting Started
Connect the sensor to any microcontroller with I2C capability, such as an Arduino or ESP32, using the labeled SDA and SCL pins. Use the DFRobot BMM350 library to initialize the sensor and begin reading magnetic field data in microteslas. The board operates at standard logic levels, but always verify voltage compatibility with your host controller.
