Arduino MIDI-in shield

Step 2 Board layout, parts list, etc.

Part list:

Resistors (1 piece each): 220 Ohms, 100 kOhms, 3.3 kOhms
Diode: 1N4148
Optocoupler: 4N28
5 PIN DIN connector (MIDI connector)
2 pinheads 1x8
1 pinhead 1x4
1 pinhead 1x6

It will also work with other Optocouplers (e.g. a 4N35, I used a 4N29)

Attached are the necessary files for etching the board and the eagle-files if you want to make modifications.
