SparkFun Micro Magnetometer - MMC5983MA (Qwiic)

The SparkFun Qwiic Micro MMC5983MA Magnetometer is a compact, 19.05mm by 7.62mm sensor that incorporates the highly sensitive triple-axis magnetometer by MEMSIC. This magnetometer is embedded in a Qwiic Micro board, which is one of the smallest in the Qwiic board series. The MMC5983MA can sense down to 0.4mG, allowing for a heading accuracy of ±0.5°. The Qwiic MMC5983MA IMU communicates over I²C by default with the Qwiic Connect System, making it easy to connect with other boards without soldering.

One of the unique features of the MMC5983MA is its built-in degaussing circuitry which helps to eliminate any residual magnetization, a common issue with most magnetometers. The sensor is also capable of output rates of 1000Hz, ±8G FSR, and 18-bit resolution, making it an excellent choice for electronic compass applications.

The SparkFun Qwiic Connect System is a series of I²C sensors, actuators, shields and cables designed to make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, which saves PCB space and ensures correct connections.

The Qwiic Micro is the smallest I²C-supported board form-factor in the series. With its compact size of 19.05mm by 7.62mm, the Qwiic Micro is perfect for projects and applications where space or weight is a concern. It has a single Qwiic connector and works well with the Qwiic Multiport or at the end of a Qwiic daisy chain.

The Qwiic Micro MMC5983MA Magnetometer features a 2.8V to 3.6V supply voltage, 1µA power down current, a fully integrated 3-axis magnetic sensor, on-chip sensitivity compensation, on-chip temperature sensor, and a max output data rate of 1000Hz. It operates with 18bits operation, 0.4mG total RMS noise, and enables heading accuracy of ±0.5º.

SparkFun has also developed a comprehensive Arduino library supporting I²C and SPI for the MMC5983MA. Simply search "SparkFun MMA5983MA" in the library manager and start measuring within minutes. This ease of use and robust support make the SparkFun Qwiic Micro MMC5983MA Magnetometer a solid choice for your sensing needs.
