Description

Description: The ADXL337 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned analog voltage outputs that measures acceleration with a full-scale range of ±3g. This board has broken out all the pins you’ll need to get the necessary data from the accelerometers. The breakout is perfect for applications like, disk drive protection, game controllers, and image stabilization.

Getting the ADXL337 Breakout set-up is easy. Simply supply the accelerometer with power (3.3V and GND), then hookup the X, Y, and Z lines of the sensor to ADC pins on your chosen development board and you will be good to go. Bandwidths can even be selected to suit the needed application, with a range of 0.5 Hz to 1600 Hz for X and Y axes and a range of 0.5 Hz to 550 Hz for the Z axis.

It should be noted that this breakout has a maximum voltage of 3.6V. Fortunately, you won’t need a lot of power to make the accelerometers work. In normal operating mode they typically draw about 300 µA.

Features:

Operating Voltage: 1.8V - 3.6V Typical Current: 300 μA Range: ±3g 3-axis sensing Bandwidth adjustment with a single capacitor per axis 1x Mounting Hole
