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 FRDM-STBA- A8961 board.
1.1 Kit Content and Packing List
The FRDM-STBA-A8961 kit contents include:
- FRDM-STBA-A8961: FXLS8961AF sensor shield board
- Quick Start Guide
2. Get to Know the Hardware
2.1 Board Features
- Sensor evaluation board for FXLS8961AF is offered as sensor shield/expansion board
- Enables quick sensor evaluation and helps accelerate quick prototyping and development using FXLS8961AF 3-axis accelerometer
- Compatible with Arduino and most NXP Freedom development boards. Can be kitted with FRDM-K22F and LPC55S16-EVK MCU boards
- Supports I²C and SPI communication interface with host MCU
- Supports hardware configurability to switch between accelerometer mode (normal vs. motion detect) and I²C/SPI interface mode
- Supports multiple test points on shield board
2.2 Board Description
The FRDM-STBA-A8961 is a sensor add-on/expansion shield board for FXLS8961AF 3-axis low-power accelerometer for automotive security and convenience applications requiring excellent offset/sensitivity stability over temperature.
FRDM-STBA-A8961 sensor shield board can be kitted optionally (order separately) with FRDM-K22F or LPC55S16-EVK MCU board to enable quick customer evaluation of FXLS8961AF using sensor toolbox enablement SW and tools.
