    MIKROE Magneto 10 Click is a compact add-on board that contains a 3D magnetometer. This board features the MLX90392, a +/-5mT range magnetometer for low-noise applications from Melexis Technologies. The MLX90392, specially designed for micropower applications, measures magnetic fields along the three axes (X, Y being in a plane parallel to the surface of the die, and Z being perpendicular to the surface). Those measurements and the MLX90392’s temperature are converted into 16-bit words, transferred upon request over I2C communication. This Click board™ is suitable for position sensing requiring a small magnetic range and precise position measurement where noise is a critical design parameter.

    Magneto 10 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

    Magneto 10 Click as its foundation uses the MLX90392, a three-axis micropower magnetic field sensor for low-noise applications based on a proprietary Triaxis technology from Melexis Technologies. The MLX90392 comes in a version of a ±5mT full-scale range for leveraging Melexis’ patented Triaxis Hall technology to deliver low noise and best-in-class accuracy. It offers a 16-bit output proportional to the magnetic flux density sensed along the XYZ axes and temperature output signal. It also features a Power-Down mode that helps save energy and maximize run-time in battery-powered applications.

    Whereas the ±5mT, the MLX90392 includes several operational modes, the sensitivity of 0.15µT/LSB and typical RMS noise down to 0.3µT. By selecting which axes are to be measured, the raw data can be used as input for further post-processing by an external MCU, making the device suitable for position sensing that requires a small magnetic range and precise position measurement where noise is a critical design parameter.

    The MLX90392 also requires a supply voltage of 1.8V to work regularly. Therefore, a small LDO regulator, BH18PB1WHFV from Rohm Semiconductor, provides 1.8V out of mikroBUS™ power rails. This LDO cut power consumption by lowering its current consumption to approximately 2μA when the application is operating in the Standby state.

    Magneto 10 Click communicates with MCU using a standard I2C 2-Wire interface that supports Standard and Fast Mode Plus operation. Since the sensor for operation requires a 1.8V logic voltage level only, this Click board™ also features the PCA9306 voltage-level translator from Texas Instruments. The I2C interface bus lines are routed to the dual bidirectional voltage-level translator, allowing this Click board™ to work with both 3.3V and 5V MCUs properly.

    This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development.
