Kit Overview

The Analog Devices EVAL-ADXL343ZEVAL-ADXL343Z is a simple breakout board that enables easy connection of an ADXL343 into an existing system. The ADXL343ADXL343 is a digital-output, 3-axis accelerometer whose low power consumption and built-in features make it ideal for use in a wide variety of applications. Due to its small size, the EVAL-ADXL343ZEVAL-ADXL343Z has minimal effect on performance of the system and of the accelerometer, and thus it is ideal for evaluation of the ADXL343ADXL343 in an existing system. Note that the ADXL343 must be communicated with digitally via SPI or I²C. No processor is included with the EVAL-ADXL343ZEVAL-ADXL343Z; firmware must be supplied externally by the user.

The ADXL343ADXL343 is a versatile 3-axis, digital-output, low g MEMS accelerometer. Selectable measurement range and bandwidth, and configurable, built-in motion detection make it suitable for sensing acceleration in a wide variety of applications. Robustness to 10,000 g of shock and a wide temperature range (−40°C to +85°C) enable use of the accelerometer even in harsh environments. The ADXL343ADXL343 measures acceleration with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either an SPI (3- or 4-wire) or I²C digital interface.

Note: For evaluation boards that include a processor, please use the EVAL-ADXL343Z-MEVAL-ADXL343Z-M and the EVAL-ADXL343Z-DBEVAL-ADXL343Z-DB please click here for more details.
