A week or so ago Max was trying to find a layout for a PICAXE 18 or 20 board with an L293/754410 motor driver. He was hoping for something similar to what sanc04 assembled.

First foray into homemade PCBs

I spent an hour or so knocking up an idea. I want to lay out my thoughts and see where it could or should go.
