    Hi, so I've made a board for my PIC18F87J60, and I was wondering if anyone would be willing to give me some feed back on it. I'm still pretty new to doing board layout with microcontrollers, so I'm not sure if I need more filtering or what not. There will be ethernet communication over the TPIN and TPOUT lines, so I'm not sure if the lengths of the wire are too long and I'll pick up too much cross talk. Advice?

    I don't have any input on the ethernet traces. However I usually put a 100uF filter cap on the input to the linear regulator and a 10uF filter cap on the output. Here's some info on that: http://www.sparkfun.com/tutorials/57

    I would wire everything up on a breadboard before getting the PCB made. Also I would put a bunch of silkscreen on the top so you can tell what goes where and what's the MCLR side of your ICSP header, etc. Sparkfun has some good Eagle tutorials, along with cam files and library files.
