Where can I find the logic voltage of the MCU in the datasheet? (I searched the pdf for "TTL", "level", and whatnot, and can't find this. I know it's in there somewhere, but I must be blind). Also, anyone who's done this before, any tips or schematics would be appreciated.
EDIT: I renamed this from "cp2103 question?", in case the word "help" gathers more attention
