EVAL-ADXRS290
ADXRS290Z Evaluation Board
Overview
Product Details
The EVAL-ADXRS290Z is a simple evaluation board that allows quick evaluation of the performance of the ADXRS290 dual-axis angular rate sensor (gyroscope). The EVAL-ADXRS290Z has two sets of 0.1 inch spaced vias, for population of 5-pin headers, for access to all power and signal lines. The vias or headers allow the evaluation board to be attached to a prototyping board (breadboard). Four holes are provided for mechanical attachment of the EVAL-ADXRS290Z to the application. An external host processor is required for communication to the part.The dimensions of the EVAL-ADXRS290Z are 20 mm × 20 mm with mounting holes set 15 mm × 15 mm at the corners of the printed circuit board (PCB).
Circuit Description
See the ADXRS290 data sheet for configuration of the accelerometer after it is connected to the application host processor.
The EVAL-ADXRS290Z has five factory installed capacitors The primary communications port is the 4-wire SPI interface. For this device, external pull-up/pull-down resistors are not required for the SPI interface, and these pins can be connected directly to the system micro controller.
Handling Considerations
The EVAL-ADXRS290Z is not reverse polarity protected. Reversing the VS or VDD I/O supply and GND pins can cause damage to the ADXRS290.
Dropping the EVAL-ADXRS290Z on a hard surface can generate several thousand g’s of acceleration, which may exceed the data sheet absolute maximum limits. See the ADXRS290 data sheet for more information.
