NXP Semiconductors LFSTBEB3110

Overview

LFSTBEB3110 from Freescale Semiconductor is an evaluation kit comprising a MAG3110 3-axis digital magnetometer and MMA8451Q 3-axis accelerometer on a sensor board, plus an adapter board for tilt-compensated eCompass demonstration with hard- and soft-iron calibration. It operates at 40 Hz sampling rate, supports µT/mg output units, and delivers calibrated compass heading, roll, and pitch angles.

For engineers reviewing the LFSTBEB3110 datasheet, LFSTBEB3110 pinout, LFSTBEB3110 application, or LFSTBEB3110 equivalent, this kit enables rapid validation of geomagnetic field measurement, real-time calibration convergence (Fit Error <2%), Smart FIFO-based orientation sampling (108–256 entries), and tilt-compensated navigation in embedded motion-sensing systems.

Technical Context

The LFSTBEB3110 kit implements a full tilt-compensated eCompass system using sensor fusion between the MAG3110 magnetometer and MMA8451Q accelerometer. Calibration relies on a configurable 10-element model (3 hard-iron coefficients + 6 inverse soft-iron matrix elements + geomagnetic field strength) solved via least-squares fitting against Smart FIFO-stored measurements.

It supports runtime configuration of magnetometer/accelerometer HAL matrices (±1, 0 alignment), low-pass filtering (16-sample default → 0.4 s 1/e time constant at 40 Hz), and calibration execution intervals from 0.25 s to 4 s - all managed through the Sensor Toolbox GUI with USB-FTDI interface.

FAQ

What is the LFSTBEB3110 and what does it contain?

The LFSTBEB3110 is a Freescale evaluation kit consisting of a sensor board integrating the MAG3110 3-axis magnetometer and MMA8451Q 3-axis accelerometer, plus an adapter board. It is not a standalone IC but a complete hardware-software system for demonstrating tilt-compensated eCompass functionality with real-time hard- and soft-iron calibration. The LFSTBEB3110 requires connection to the LFSTBUSB interface board and Sensor Toolbox software to operate.

Does the LFSTBEB3110 include firmware or software?

Yes - the LFSTBEB3110 is intended for use with Freescale's free Sensor Toolbox software, which provides the eCompass application, calibration algorithms, real-time visualization (3D Pointer, Navigation), and data logging. The kit ships with the LFSTBEB3110 Quick Start Guide and relies on host PC execution; no onboard programmable memory or user-loadable firmware is included with the LFSTBEB3110 itself.

Can the LFSTBEB3110 be used without the LFSTBUSB board?

No - the LFSTBEB3110 sensor and adapter boards are designed exclusively for mechanical and electrical interfacing with the LFSTBUSB USB-interface board. They lack native USB connectivity or power regulation; operation requires the LFSTBUSB board to provide USB power, FTDI serial bridging, and physical mounting. The LFSTBEB3110 cannot function as a standalone USB device.

What calibration models does the LFSTBEB3110 support?

The LFSTBEB3110 supports three calibration models via Sensor Toolbox: 10-element (full hard-iron vector + symmetric inverse soft-iron matrix + geomagnetic field), 7-element (diagonal soft-iron matrix only), and 4-element (hard-iron vector + scalar field). Each reduces parameter count and computation load while increasing Fit Error - the 10-element model is required to achieve the <2% Fit Error needed for "Calibrated" status in the LFSTBEB3110 GUI.

Is the LFSTBEB3110 RoHS-compliant and lead-free?

Yes - per Freescale's 2011 documentation (MAG3110UG Rev. 2), RoHS-compliant and Pb-free versions of Freescale products, including those in the LFSTBEB3110 kit, maintain identical functionality and electrical characteristics as non-RoHS counterparts. Compliance aligns with Freescale's Environmental Products program and applies to both the MAG3110 and MMA8451Q components on the LFSTBEB3110 sensor board.
