IMPORTANT NOTICE
For engineering development or evaluation purposes only
NXP provides the product under the following conditions:
This evaluation kit is for use of ENGINEERING DEVELOPMENT OR EVALUATION PURPOSES ONLY. It is provided as a sample IC presoldered to a printed-circuit board to make it easier to access inputs, outputs and supply terminals. This evaluation board may be used with any development system or other source of I/O signals by connecting it to the host MCU computer board via off-the-shelf cables. This evaluation board is not a Reference Design and is not intended to represent a final design recommendation for any particular application. Final device in an application heavily depends on proper printed-circuit board layout and heat sinking design as well as attention to supply filtering, transient suppression, and I/O signal quality.
The product provided may not be complete in terms of required design, marketing, and or manufacturing related protective considerations, including product safety measures typically found in the end device incorporating the product. Due to the open construction of the product, it is the responsibility of the user to take all appropriate precautions for electric discharge. In order to minimize risks associated with the customers' applications, adequate design and operating safeguards must be provided by the customer to minimize inherent or procedural hazards. For any safety concerns, contact NXP sales and technical support services.

3.3 Static handling requirements

CAUTION

This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken during transport and handling. You must use a ground strap or touch the PC case or other grounded source before unpacking or handling the hardware.

3.4 Minimum system requirements
The FRDMSTBI-NMH1000 evaluation board requires a Windows 10 PC workstation and a Freedom FRDM-KE15Z MCU board.
3.5 Software
Installing software is necessary to work with this evaluation board. All listed software is available on the evaluation board's information page at https://www.nxp.com/products/ sensors/magnetic-sensors/nmh1000-ultra-low-power-and-low-voltage-magneticswitch:NMH1000.
4 Getting to know the hardware

4.1 Kit overview
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 (See Section 5 "Configuring the hardware"). The following board is recommended:
· FRDM-KE15Z
The user can connect the two boards for evaluation of the NMH1000 magnetic sensor with either a terminal program using the NXP provided Component Library Section 5 "Configuring the hardware" or standalone use. In either use case, the hardware helps users in their software development.
These evaluation boards provide an intuitive way to change between the sensors standalone modes and using the I2C interface for communication through jumper selections as well as providing test points that are typically used for evaluation. The NMH1000 datasheet provides additional information and configuration details.
4.2 NMH1000 magnetic sensor 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
