• FXLS8961AF[2]: 3-axis digital accelerometer
  The FRDM-STBA-A8961 sensor board enables quick customer evaluation of the FXLS8961AF using the sensor toolbox enablement software and tools.

Board features

• Sensor shield/expansion board for the FXLS8961AF – 3-axis accelerometer for automotive security and convenience applications requiring excellent offset/sensitivity stability over temperature.
• Compatible with Arduino® and most NXP Freedom development boards. This sensor shield board can be kitted with LPC55S16-EVK or FRDM-K22F MCU boards.
• Enables quick sensor evaluation and helps accelerate quick prototyping and development.
• 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-STBA-A8961 sensor shield board can be powered up by the LPC55S16-EVK or the FRDM-K22F 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 MCU board to the PC via the USB cable between the LINK2 or OpenSDA USB port on the MCU board and the USB connector on the PC.
