Triple Axis Magnetometer Qwiic Breakout - MLX90393

SparkFun SEN-14571

It's time to start utilizing the superior magnetometer! What better way than to throw it onto an easy-to-use breakout board? The SparkFun MLX90393 Magnetometer Breakout is a triple-axis magnetic sensor board capable of sensing very small fields. All the while still behaving as one would expect during saturation in larger fields (like a nearby magnet). The MLX90393 breakout works well as a compass sensor however also as a non-contact controller, flow meter with magnetic impeller, or a linear actuator position sensor. Making it even easier to get your readings, all communication enacts exclusively via I²C, utilizing our handy Qwiic system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.
The MLX90393 features a resolution rate of 0.161µT with an operating voltage range of 2.2V to 3.6V at 100µA. This breakout is equipped with jumper pads on the back of the board. A set that allows you to change the I²C address as well as one that can put the breakout into SPI mode (if I²C isn't your cup of tea).

Features:

• Operating Voltage: 2.2V-3.6V
• Current Consumption: 100µA (Typ.)
• Operating Temperature: -20°C - 85°C
• Resolution: 0.161µT
• Max Full Scale Resolution: 44,000µT
• I²C Address: 0xC0
• 2x Qwiic Connection Ports

Board Pin Layout:

• 3.3V: Power Supply Input Should be between 2.2V - 3.6V
• GND: Ground Input 0V/common voltage
• SDA: I2C Data Signal Bi-directional Bi-directional data line. Voltage should not exceed the power supply (e.g. 3.3V)
• SCL/SCLK: I2C Clock Signal Input Master-controlled clock signal. Voltage should not exceed the power supply (e.g. 3.3V)
• CS: Chip Select Input Chip Select pin, digital input. Tied high for I2C operation, cut trace jumper and tie low for SPI
• INT: Interrupt Output Interrupt pin, active high, digital output. Also configurable as a data ready pin
• TRIG: Reset Input/Output Trigger pin, active high, digital output. Also configurable as an interrupt pin
