Good morning

Good plan. SPI should be kept free for things like that.

However WRT chip has a bug which never releases. But some people have =
fixed it, e.g. Jon Oxer - =
http://www.freetronics.com/products/ethernet-shield-with-poe. Some =
setups also use pin 2 for interrupt, which you use for IR sensor.

0,1 - Serial
2 - IR Sensor or Ethernet shield. If you use a Wifi shield it does use =
pin 2
3 ?
4,5,6,7 =3D Sink
8,9,10,11 =3D Source

So... what is best? Not totally sure, but maybe
	0,1 Serial
	2 - Spare or Shield
	3 - IR sensor (does it have interrupts)
	4,5,6,7 =3D Sink (can you use one as PWM)
	8 ?
	9 =3D USB select?
	10 =3D standard used for ethernet shield select
	11-13 =3D SPI
	Which still leaves the source driver, although I know it works =
14,15,16,17

Always hard. I do like that you just did those little solder pads that =
took me no more than 15 minutes to organise move and test. While things =
like my ethernet and wifi shields are not configurable without extreme =
cutting.

So in what form are you adding USB? Normally USB on Arduino is just =
converted from the serial port (pin 0,1).

that shows how to move the pins:

Yes got that, the day after I did it... thehe :-)
It will be boring but I will post a photo.

BTW. If you google Lightuino - the majority of the links lead to the =
Google code site, which has lots of info on V2 hardware, and none on v3. =
I think you should create a v3 page there and link it to your private =
site.
