Description

The SparkFun Micro Magnetometer Breakout centers on the MEMSIC MMC5983MA, a high-performance MEMS 3-axis magnetometer. It delivers precise magnetic field Vector Technics measurements with a full-scale range of ±8 Gauss and 18-bit digital resolution, enabling detailed environmental magnetic mapping and accurate heading calculation. The sensor’s high sensitivity (0.4mG RMS noise) and integrated degaussing function ensure stable readings by neutralizing residual magnetization, while the on-chip temperature sensor provides data for thermal compensation.

Designed for seamless system integration, the breakout utilizes the Qwiic connector system for plug-and-play I2C connectivity, eliminating the need for soldering. Its minimal 0.75″ x 0.30″ footprint makes it ideal for compact embedded applications in portable navigation devices, robotic positioning systems, and motion tracking platforms. The board operates from a 2.8V to 3.6V supply, making it compatible with common 3.3V logic microcontrollers like those from the Arduino, Raspberry Pi, and ESP32 families.

Frequently Asked Questions

What is the operating voltage range for this MMC5983MA breakout board?

The board requires a supply voltage between 2.8V and 3.6V. It is designed for use with standard 3.3V logic systems commonly found on Arduino, Raspberry Pi, and ESP32 platforms. Exceeding this range may damage the sensor.

How do I connect and communicate with this sensor?

Connection is simplified via the Qwiic I2C connector system—simply plug in a Qwiic cable. Communication uses the I2C protocol with a default device address of 0x30. No soldering is required for basic operation, and libraries are available from SparkFun to facilitate data reading.

What is the purpose of the built-in degaussing feature?

The on-chip degaussing circuitry generates a brief magnetic field pulse to neutralize any residual magnetization within the sensor core. This function helps maintain measurement accuracy over time by resetting magnetic offsets, which is crucial for precise compass heading calculations.

Can this sensor be used for high-speed motion tracking?

Yes, the MMC5983MA supports a configurable output data rate of up to 1000 Hz, making it suitable for dynamic, real-time motion tracking applications. The high data rate, combined with its 18-bit resolution, provides detailed magnetic field data for fast-updating orientation systems.

Is the sensor's data affected by temperature changes?

The MMC5983MA includes an integrated temperature sensor. While temperature can affect magnetic sensitivity, the on-chip compensation and the availability of temperature data allow for software-based correction if required, ensuring stable performance across its operating temperature range.
