SparkFun Triple Axis Accelerometer Breakout - ADXL335

 

Breakout board for the 3 axis ADXL335 from Analog Devices. This is the latest in a long, proven line of analog sensors - the holy grail of accelerometers. The ADXL335 is a triple axis MEMS accelerometer with extremely low noise and power consumption only 320 uA. The sensor has a full sensing range of +/- 3g. There is no on-board regulation, provided power should be between 1.8 and 3.6 Volt. Board comes fully assembled and tested with external components installed. The included 0.1 uF capacitors set the bandwidth of each axis to 50 Hz.
