Figure 4 in the guide shows you how to connect the adxl345z for i2c mode. Vs must be supplied(3.3 V is OK). See this <a href="https://www.element14.com/community/servlet/JiveServlet/downloadBody/52047-102-3-270225/ADI.Datasheet_1.pdf">data sheet</a> for more information, take a look at the POWER SEQUENCING chapter (page 13).</p><div style="clear:both;"></div>
