The ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±3 g. ![enter image description here][1] The module was designed as breakout board because ADXL335's signal is analog( more ports requested ),but the board outline is grove module that you can fix it convenient like others grove. The sensor combine 3.3 and 5V power supply,can be used in standard arduino device and seeeduino stalker. Features Wide power range DC3V to 5V Grove module 3 axis sensing Small, low-profile package: 4×4×1.45mm LFCSP Low power 350µA at 3V (typical) High sensitive 10,000 g shock survival BW adjustment with a single capacitor per axis RoHS/WEEE lead-free compliant [1]: http://www.seeedstudio.com/depot/bmz_cache/0/0ba59f18642b6c5c2c6d51d5d31d383e.image.530x397.JPG
