Melexis Technologies NV EVB90392_BK_011

Overview

EVB90392_BK_011 from Melexis is a breakout evaluation board for the MLX90392ELQ-AAA-011 3-axis Hall-effect magnetic sensor, supporting ±50 mT full-scale range, operating at 1.8 V only, and communicating via I²C at default 100 kHz with fixed 7-bit address 0x0C. It enables rapid prototyping of position, angle, and current sensing in industrial and automotive subsystems.

For engineers reviewing the EVB90392_BK_011 datasheet, pinout, applications, or equivalent options, this board provides direct access to raw XYZT magnetic and temperature measurements, configurable filter settings, continuous 100 Hz measurement mode, and GUI-driven register-level control - all on a compact 25 mm × 35 mm PCB with unpopulated level-shifting components.

Technical Context

The EVB90392_BK_011 implements a minimal breakout interface for the MLX90392ELQ-AAA-011 IC, routing only the four essential pins (VDD, GND, SDA, SCL) to a 4-pin header without voltage regulation or level shifting. It relies on external 1.8 V supply and requires either a 1.8 V microcontroller or external level translation for host interfacing.

Communication uses standard I²C protocol with fixed 7-bit address 0x0C; serial command interface (9600 baud, 8N1) bridges PC-to-microcontroller commands for register read/write, mode configuration (e.g., single/continuous measurement), and filter tuning. All firmware and GUI tools are provided as-is for demonstration purposes only.

FAQ

What is the primary function of the EVB90392_BK_011?

The EVB90392_BK_011 is a breakout evaluation board for the MLX90392ELQ-AAA-011 magnetic sensor IC. It provides direct access to the sensor's I²C interface and raw measurement outputs (XYZ magnetic field + temperature) without onboard regulation or level shifting. The EVB90392_BK_011 enables rapid validation of sensor behavior in lab and prototype environments, supporting register-level configuration and continuous 100 Hz data streaming.

Does the EVB90392_BK_011 include a voltage regulator or level shifter?

No, the EVB90392_BK_011 does not include a voltage regulator or level shifter. It is the "breakout" variant, meaning only the MLX90392ELQ-AAA-011 IC and a 100 nF decoupling capacitor are mounted, with VDD, GND, SDA, and SCL routed directly to a 4-pin header. Users must supply a clean 1.8 V source and ensure I²C signal levels match - either via a 1.8 V microcontroller or external level translation circuitry when interfacing with 3.3 V hosts.

What I²C address does the EVB90392_BK_011 use?

The EVB90392_BK_011 uses a fixed 7-bit I²C address of 0x0C for all communication with the MLX90392ELQ-AAA-011 sensor. This corresponds to write address 0x18 and read address 0x19. The address is hardwired and not configurable on the EVB90392_BK_011 - no pull-up/pull-down resistors or DIP switches are present to modify it.

Can the EVB90392_BK_011 perform continuous magnetic measurements?

Yes, the EVB90392_BK_011 supports continuous XYZT measurement mode at 100 Hz by writing value 0x05 to register 0x10 of the MLX90392ELQ-AAA-011. Data can then be read repeatedly from register 0x00, returning 10 bytes per frame (X, Y, Z, status, temperature LSB/MSB). This mode is fully functional on the EVB90392_BK_011 when used with compatible firmware and host software such as the provided LabVIEW GUI.

What software tools are provided for the EVB90392_BK_011?

Melexis provides a LabVIEW-based GUI executable and Arduino-compatible firmware (.ino) for the EVB90392_BK_011. The GUI implements all documented I²C commands (read/write registers, change I²C frequency, set measurement mode), displays real-time XYZT data, and supports CSV logging. The firmware handles serial-to-I²C bridging at 9600 baud. Both are distributed as-is for demonstration - no warranty or error guarantee is provided.
