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 7.4V battery because its too high.
