The is a simple evaluation board that allows quick evaluation of the performance of the 3-axis digital accelerometer. The 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 are 20 mm × 20 mm with mounting holes set 15 mm × 15 mm at the corners of the printed circuit board (PCB).
Note: The is not reverse polarity protected. Reversing the VS or VDD I/O supply and GND pins can cause damage to the . Dropping the 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.
