The 7Semi MMC5983MA Mini Magnetometer Breakout is a compact and highly sensitive 3-axis magnetic sensor designed for precision applications. Utilizing MEMSIC's MMC5983MA technology, it offers a resolution of 0.4mG and heading accuracy of ±0.5°, making it ideal for electronic compass and navigation systems. The sensor features a ±8G full-scale range and operates with an 18-bit resolution, providing detailed magnetic field measurements. Communication is facilitated via I²C interface with a default address of 0x30, supporting data rates up to 1000Hz. Its low-power design, consuming only 1µA in power-down mode, ensures energy efficiency. The breakout board includes built-in degaussing circuitry, mitigating residual magnetization effects. Its compact form factor with a 4-pin 2mm pitch JST connector simplifies integration into various projects. This sensor is suitable for applications in robotics, drones, and other systems requiring precise magnetic field sensing.
