On a somewhat related note, I was thinking about using some sort of epoxy or other goopy compound to seal all the parts on the board, particularly the .05" header, from metal chips and any other potential source of shorts. Know of anything that would be fairly easy to apply and non-conductive?
I've used This before and it works well. I do HIGHLY recommend that you use it in a WELL ventilated area.
A low temp drying oven is the recommended way to cure this.

Now that you mention conformal coating it, I've also heard that it's possible to use nail polish as well. A spray-on like you suggested would probably work better though, speed up production of the 20-odd boards that I'm going to be making. I'll probably stick some tape over the solder pads to avoid coating those, as we need those for the board to work.

Re: Rate my Talon SRX breakout (EagleCAD)

I'm jumping in probably a bit late and I'm short on time, so sorry if you've already though through this.

Q1/Q2 should likely be a MOSFET, right? Otherwise any voltage applied to the encoder pins will be pulled hard down by the transistor. You could put a resistor in series with the gate, but that will require a constant current draw.

We've been using latching molex connectors for quite a while and have liked them a lot. Consider connectors instead of soldering wires down.

Re: Rate my Talon SRX breakout (EagleCAD)

Take a look at the attachments. This is what our team has used for the last two years.. They have worked great, keep our wiring in order and allows for easy trouble shooting and placement on the robot.
