Min Voltage For IO Tiny

I am working on the T3-DO project from Michael Baddeley Printed Droid.  I am planning on using the IO Tiny with MG90 and FS90R servos.  These are basically max 6V servos.   Does the IO Tiny regulate voltage?  My guess is no as I am pretty sure the EZ-BV4 does not either.  So, what is the min voltage for the IO Tiny? I don't want to use the EZ-Robot...

Ultrasonic Distance Sensor

Can you confirm whether the Ultrasonic Distance Sensor (Collision) works with the Mobile App? Comments from 2017 suggests not, and it doesn't work for me. Works fine with ARC.

I am neck deep  in programming my "Simone" robot. I know that I can use multiple or nested if/elseif/then statements, but what would really make my life easier would be a "switch / case statement." switch(expression) { case constant-expression : statement(s); break;  case constant-expression : statement(s); break; ...
