Yaesu Band Data Ver.2

Yet another Yaesu Band Data Decoder. It is similar to the last version (ver 1.0) but it doesn't use relay. This board uses a power driver integrated circuit (ULN 2003). Each output, when active, provide 12V with a maximum current of 500mA (max continuous load) sufficient to drive the most common relay.

This board is easy to build and requires less components than the ver.1.0. Pay attention to not overload the outputs of the ULN2003 or it will die.
