Analog Devices: EVAL-ADXL345Z Accelerometer Evaluation Board

The EVAL-ADXL345ZEVAL-ADXL345Z is a simple evaluation board that allows quick evaluation of the performance of the ADXL345ADXL345 3-axis digital accelerometer. The EVAL-ADXL345Z has two sets of 0.1 inch spaced vias, for population of a 4-pin and 5-pin header, for access to all power and signal lines. The vias or headers allow the evaluation board to be attached to a prototyping board (breadboard) or attached to the PCB in an existing system.Four holes are provided for mechanical attachment of the EVAL-ADXL345Z to the application.

An external host processor is required for communication to the part. The dimensions of the EVAL-ADXL345Z are 20 mm × 20 mm with mounting holes set 15 mm × 15 mm at the corners of the printed circuit board (PCB).

• The EVAL-ADXL345ZEVAL-ADXL345Z is a simple breakout board that enables easy connection of an ADXL345ADXL345 into an existing system.
• The ADXL345 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-ADXL345Z has minimal effect on performance of the system and of the accelerometer, and thus it is ideal for evaluation of the ADXL345 in an existing system.
• Note that the ADXL345 must be communicated with digitally via SPI or I2C. No processor is included with the EVAL-ADXL345Z; firmware must be supplied externally by the user.
• The ADXL345BCCZ.ADXL345BCCZ. is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0°

Note: The EVAL-ADXL345ZEVAL-ADXL345Z is not reverse polarity protected. Reversing the VS or VDD I/O supply and GND pins can cause damage to the ADXL345ADXL345. Dropping the EVAL-ADXL345Z on a hard surface can generate several thousand g’s of acceleration, which may exceed the data sheet absolute maximum limits.

Key Applications: Handsets, Medical instrumentation, Gaming and pointing devices Industrial instrumentation, Personal navigation devices, Hard disk drive (HDD) protection.
