1.Interface: 1) + connect to DC1.8~3.6V2) - connect to GND3) X is analog data output of X axis 4) Y is analog data output of Y axis5) Z is analog data output of Z axis 2. Specification: 1) working temperature: -40 to 85°C 2) sensitivity: 300mv/g3) Sensitivity accuracy: +/-10 % 4) Output method: SPI, I2C analog output5) Bandwidth: 1.6KHZ 6) Working voltage: 1.8~3.6V 3. Usage instruction: The module is easy to use, just connect the output X, Y and Z to Arduino analog ports A0, A1, A2. Also, we connect reference voltage AD to 3.3V. Do remember to power up the module, otherwise, the module cannot work.  4. Attentions: Pay attention to power supply; when we are using the 3.3V port of Arduino, do not connect to 5V power supply to avoid malfunction of the module. Besides, the module outputs are analog, so you need to connect it to analog ports.
