Proto I/Os Rev. B

In this revision i didn't add any new component or changed any electric connection, so basically the schematic is the same has in the previous revision.

And here are the files for the schematic and the PCB.

The improvements and/or addings

I also added a diferent header this time, its a female header with bigger pins, this way in one build we can use it in a breadboard or on a the table with wire to the header or even both.
