The ADXL321EB is a simple evaluation board that allows quick evaluation of the performance of the ADXL321 dual-axis ±18g Accelerometer. The ADXL321EB has a 5pin, 0.1 inch spaced header for access to all power and signal lines which the user can attach to a prototyping board (breadboard) or wire using a standard plug. Four holes are provided for mechanical attachment of the ADXL321EB to the application. The ADXL321EB is 20mm × 20mm with mounting holes set 15mm × 15mm at the corners of the PCB. The ADXL321EB has two factory-installed 100nF capacitors (C2 and C3) at Xout and Yout to reduce the bandwidth to 50Hz. Many applications require a different bandwidth, in which case the user can change C2 and C3, as appropriate.
