* '''Vio''' - '''{{underline|THIS IS THE MOST IMPORTANT PIN}}'''! This is the pin that you MUST drive with an external voltage from 3V-5V to set the logic level converter. The converter '''also buffers the indicator LEDs''' so NOTHING will appear to work unless this pin is powered! You should set the voltage to whatever voltage your microcontroller uses for logic. A 5V micro (like Arduino) should have it be 5V, a 3V logic micro should set it to 3V. | * '''Vio''' - '''{{underline|THIS IS THE MOST IMPORTANT PIN}}'''!
