Triple Axis Magnetometer - MMC5983MA (Qwiic)

Added to your shopping cart

The MMC5983MA is a highly sensitive triple axis magnetometer by MEMSIC. It is capable of sensing down to 0.4mG enabling a heading accuracy of ±0.5°. Output rates of 1000Hz, ±8G FSR, and 18-bit resolution make the MMC5983MA a phenomenal magnetic sensor for electronic compass applications.

Saturation is a problem for all mag sensors. The MMC5983MA has special built-in degaussing circuitry to clear any residual magnetization.

We've got a feature complete Arduino library supporting I2C and SPI. Just search SparkFun MMA5983MA in the library manager and get measuring within minutes.

We do not plan to regularly produce SparkX products so get them while they’re hot!


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.

Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.

  • Is there any documentation for the hardware interface to this MMC5983MA magnetometer? I notice there are some jumper pads for the interface protocol. Any thing on that?
