Подробнее о продуктеThe 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).
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.
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.
