Elecbee CJMCU-90393 MLX90393 Digital 3-Axis Hall Sensor Module, 3.3 V, 16-Bit XYZ and Temperature Output, I2C/SPI

MLX90393 · 3-AXIS MAGNETIC SENSOR · I2C / SPI

Digital Magnetic Sensing for Position-Control Projects

The Elecbee CJMCU-90393 breakout exposes the MLX90393 Triaxis Hall sensor through labeled I2C and SPI connections, giving a host controller 16-bit X, Y and Z magnetic-field data plus temperature data.

SENSOR OUTPUT

Measure Three Magnetic Axes Digitally

The MLX90393 measures magnetic flux density along the X, Y and Z axes and supplies a separate temperature reading. Each output is 16-bit digital data. Programmable gain provides a 5–50 mT dynamic range, while configurable measurement modes let the controller select the axes and operating behavior needed by the application.

INTERFACES

Choose I2C or SPI for Host Communication

For I2C integration, use SDA and SCL. For SPI integration, use MOSI, MISO, SCLK and CS; the MLX90393 supports SPI communication up to 10 MHz. TRIG can initiate acquisition and INT can indicate configured field-change events.

The underside provides A0 and A1 address-selection solder jumpers as well as a CS pull-up configuration area. Confirm jumper states and the selected protocol before connecting the module to a controller.

APPLICATIONS

A Sensor Platform for Magnet-Based Controls

Use the module to develop non-contact rotary knobs, linear controls, joysticks, sliding switches, closure detection and other magnetic HMI or position-sensing systems. Performance depends on the magnet, distance, orientation, mechanical geometry, gain settings and calibration implemented by the host system.
