1. Out of the Box

The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost, and improved performance in powering state-of-the-art systems.

This page will guide you through the process of setting up and using the FRDMSTBI-NMH1000 board.

1.1 Kit Content and Packing List

The FRDMSTBI-NMH1000 contents include:

  • FRDMSTBI-NMH1000 shield board with Arduino headers

1.2 Additional Hardware

The FRDMSTBI-NMH1000 can be paired with NXP MCU boards of your choice, however there is a demo project provided for the FRDM-KE15Z MCU board for evaluation.

1.3 Static Handling Requirements

1.4 Minimum System Requirements

The FRDMSTBI-NMH1000 evaluation board requires a Windows 10 PC workstation and a Freedom FRDM-KE15Z MCU board.

2.1 Board Features

The NMH1000 is a hall effect magnetic field sensor that is most sensitive to a vertical field passing through the top-to-bottom surfaces, orthogonal to the plane of the application printed circuit board. The sensor operates at low voltage, low current, low output data rate, and is a small physical size. Features include:

  • Z- axis Hall effect switch for axial magnets
    • North and South polarity sensitivity
  • Low operating voltage down to 1.2 V
  • Ultra-low power consumption
    • 75 nA typ. @ 1 Hz sample rate
  • Industrial operating temperature range
    • –40 °C to 85 °C
  • Selectable Modes
    • Standalone Mode
      • Threshold selection 3-state hardware pin (70 Guass, 140 Gauss or 210 Gauss)
      • Samples rate selection 3-state hardware pin (0.1 Hz, 1.0 Hz, 10 Hz)
    • I2C User Mode
      • Threshold selection data bits
      • Sample rate selection data bits (0.1 Hz to 100 Hz)
  • Binary state hardware pin output; programmable polarity in I2C User Mode
  • Small Form Factor Packaging
    • DFN 1.4 x 1.4 x 0.85 mm
    • 6 pins, 0.5 mm pitch

2.2 Board Description

The FRDMSTBI-NMH1000 shield board incorporates a NMH1000 fully integrated magnetic sensor that provides a small footprint, low current and low operating voltage, I2C mode or standalone mode capabilities.

The FRDMSTBI-NMH1000 shield board can be easily connected to a NXP Freedom MCU board via the Arduino headers for evaluation.

2.3 Board Components

Overview of the FRDMSTBI-NMH1000 board

The FRDMSTBI-NMH1000 shield board comes with standard Arduino headers and can be paired with NXP Freedom MCU boards for user evaluations and software development. For quick evaluation and prototyping, NXP provides a demo project targeted to the FRDM-KE15Z board and the hardware design files for fast time to market.
