SparkFun Micro Magnetometer - MMC5983MA (Qwiic)

Stock code: SEN-19921

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. We've attached the magnetometer IC onto an incredibly small Qwiic board form factor that we like to call 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 our 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.

We'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.


The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Qwiic Micro is our smallest I2C-supported board form-factor yet! At only 0.75in. by 0.30in. (or 24.65mm by 7.62mm for metric friends), Qwiic Micro is perfect for projects and applications that have space or weight concerns. With just a single Qwiic connector, Micro boards work great alongside the Qwiic Multiport or at the end of a Qwiic daisy chain.
