This is the USBTag. As usual all my designs are meant to save breadboard space so this is TINY as well. This board, as do all my others which require 3.3v uses the SP6205 (500mA) voltage regulator. I love this regulator as it performs great! If you notice in the schematic C1 isnt needed but i like to include it to ensure even more stability in all my designs. This board breaks out all the USB pins and gives you another power pin 3.3v. The board is meant to fit in the middle of a breadboard hanging off. This means almost no space is used.
