9-29-2014: This update just adds the zip file containing the board in its current layout. Send the zip file to your favorite board house and get your own stack of boards. :) I still have a few that I am dispersing.

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.
