I am using the EVAL-ADXL345Z and noticed that - unlike to evaluation boards from other suppliers - Vs and Vio have an own pin each. I am wondering what the purpose of this is, since both require 3.3V. Is there a recommendation if the pins should have a common or separated voltage supplies?


Thank you very much.
