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.
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.
