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.

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)
-
