Introduction to FRDM-STBI-A8971 sensor toolbox development board
4 Getting to know the hardware
4.1 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.
4.2 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 I
2
C and SPI communication interface with the host MCU.
• Supports hardware configurability to Switch Accelerometer mode (normal vs motion detect) and I
2
C/SPI
Interface mode.
• Supports multiple test points on the board.
4.3 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.
