Micro Magnetometer - MMC5983MA (Qwiic)

DESCRIPTION

The SparkFun Qwiic Micro MMC5983MA Magnetometer is a micro-sized, 0.75in. by 0.30in. sensor that utilizes the highly sensitive triple-axis magnetometer by MEMSIC. They've attached the magnetometer IC onto an incredibly small Qwiic board form factor called Qwiic Micro! The MMC5983MA is capable of sensing down to 0.4mG, enabling a heading accuracy of ±0.5°. The Qwiic MMC5983MA IMU communicates over I²C by default utilizing the handy Qwiic Connect System, so no soldering is required to connect it to the rest of your boards.

Saturation is a problem for all mag sensors. The MMC5983MA has built-in degaussing circuitry to clear any residual magnetization. Output rates of 1000Hz, ±8G FSR, and 18-bit resolution make the MMC5983MA a phenomenal magnetic sensor for electronic compass applications.

They've also written a feature-complete Arduino library supporting I²C and SPI. Just search "SparkFun MMA5983MA" in the library manager and start measuring within minutes.
