There are two options for evaluating the ADXRS290. One is a simple breakout board (EVAL-ADXRS290Z) and the other is a GUI based real-time evaluation system (EVAL-ADXRS290Z-M/M2).
The EVAL-ADXRS290Z allows for quick evaluation of the ADXRS290 dual-axis angular rate sensor. 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 also provided for mechanical attachment of the EVAL-ADXRS290Z to customer applications. 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).
The schematic of the EVAL-ADXRS290Z is shown below. See the ADXRS290 datasheet for configuration of the accelerometer after it is connected to the application host processor.
The PCB layout of the EVAL-ADXRS290Z is shown below. 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.
Details of the GUI based real time evaluation system is described in Part 2 of this document.
Part 2 has been added.
Hi Venkat, Where is Part 2 of this? Where can I find a detailed explanation of the various evaluation boards? M, M2, S, S2...? Thanks, Bill
