    The Analog Devices ADXL203EB is a simple breakout board that allows quick evaluation of the performance of the ADXL203CE accelerometer. The ADXL203 is a 2-axis, low-noise, temperature-stable accelerometer. The small size (1" x 1") of the ADXL203CE makes it easy to mount the accelerometer to an existing system without the need for additional hardware and with minimal effect on performance of the system and of the accelerometer.

    The ADXL203EB has a 5-pin 0.1 inch spaced header for access to all power and signal lines that the user can attach to a prototyping board (breadboard) or wire using a standard plug. Four holes are provided for mechanical attachment of the ADXL203EB to the application. The ADXL203EB has two factory-installed 100 nF capacitors (C2 and C3) at XOUT and YOUT to reduce the bandwidth to 50 Hz. However, many applications require a different bandwidth, in which case the user can change C2 and C3, as appropriate. The ADXL203EB is 20 mm × 20 mm, with mounting holes set 15 mm × 15 mm at the corners of the PCB.

    Key Applications: Vehicle dynamic controls, Electronic chassis controls, Platform stabilization/leveling, Navigation, Alarms and motion detectors, High accuracy, 2-axis tilt sensing, Vibration monitoring and compensation, Abuse event detection
