This is one of my first times using eagle, so I wanted to run this by people with (hopefully!) a bit more expirience.

It is basically just a shield for the little LCD sparkfun sells: http://www.sparkfun.com/commerce/product_info.php?products_id=709
I know the pinouts are different from the standard 4bit LCD library, I modified the library to match the pcb design, and have it all set up on a breadboard on my desk at the moment (it works! so happy!).

Does anyone see any problems with this? Stuff that may not be obvious to a newbie like I measured wrong or when I start soldering it's going to rub against stuff underneath... etc.

It isn't completely finished yet, my project requires a few more pins that I'm going to bring off to the side, but I wanted to post it in case anyone was looking for something like this before I make the customizations for my project.



There's a gap between digital pins 7 and 8 on the Arduino board that I didn't see in your design.  Note that the gap is slightly thinner than the space taken up by one of the pins.


oh shoot, you're right I didn't even see that looking at the board :-p

do you have a width on that? Looks like about 2mm to me

It seems to be 4mm. So about 1mm less than the normal 2x0.1" spacing.


You could download the Arduino serial eagle files (http://www.potemkin.org/uploads/Pid/arduino_rs232_v2.zip) and check that for the spacing.


Done, and I will. Only reason I didn't start off with that is because I've never used eagle before :-p but I learned a bit while making my little diagram so hopefully when I get a few minutes we'll learn some more!


ok, by my (uneducated) measurements, the gap is 150mil, my sch/brd/png have all been updated.

Anything else?
