Getting to know the hardware

Kit overview
The FRDM-STBI-A8971 sensor evaluation board is offered as a sensor kit with the LPC55S16-EVK. The sensor shield board includes the following sensor part:

• FXLS89671CF[2]: 3-axis digital accelerometer

The FRDM-STBI-A8971 sensor kit enables quick customer evaluation of the FXLS8971CF using the sensor toolbox enablement software and tools.

Board features

• Sensor evaluation and development kit for the FXLS8971CF.
• Enables quick sensor evaluation and helps accelerate quick prototyping, development using NXP sensors.
• Compatible with Arduino® and most NXP Freedom development boards.
• Allows evaluation of current consumption and pin-voltage characteristics.
• Supports I2C and SPI communication interface with the host MCU.
• Supports hardware configurability to Switch Accelerometer mode (normal vs motion detect) and I2C/SPI Interface mode.
• Supports multiple test points on the board.

Kit featured components
The combination of a shield development board and a freedom development MCU board enable a complete solution for quick sensor evaluation, prototyping, and development using the sensor toolbox development ecosystem.
The board is designed to be fully compatible with Arduino I/O headers and optimized for the operating conditions. The FRDM-STBI-A8971 sensor shield board is powered up by the LPC55S16-EVK MCU board by stacking the shield board on top of the MCU board using Arduino I/O headers, as shown in Figure 2, and connecting the LPC55S16-EVK to the PC via the USB cable between the LINK2 USB port on the MCU board and the USB connector on the PC.

This sensor kit is enabled with the FreeMASTER-Sensor-Tool software tool[6] providing an out-of-box demonstration GUI. The sensor toolbox ecosystem collaterals enable end users to move through each phase of product development quickly and increase ease of use.

Schematic, board layout and bill of materials
The schematic, board layout and bill of materials for the FRDM-STBI-A8971 evaluation board are available at www.nxp.com/FXLS8971CF.

Configuring the hardware

1. Check and confirm the FRDM-STBI-A8971 sensor shield board settings as described below:
   • To select the I2C digital interface, connect pins 2-3 of SW2 on the FRDM-STBI-A8971.
   • Connect pins J7, J8 pins 1-2 to select I2C0 pins on the shield board.
   • To select the SPI digital interface, connect pins 1-2 of SW2 on the FRDM-STBI-A8971.
   • Connect pins 2-3 of SW1 to select the default Accelerometer Operating mode, that is, ACCEL NORMAL mode.
2. Connect the FRDM-STBI-A8971 sensor shield board to the LPC55S16-EVK MCU board on the Arduino I/O headers.
3. Connect the sensor evaluation kit (FRDM-STBI-A8971 kitted with the LPC55S16-EVK) to a windows PC via the USB cable between the LINK2 USB port on the board and the USB connector on the PC.
