Make a Rugged Stepper Driver

First part of my two part project to create a decent rugged stepper driver board is complete.

The project is written up as far as it goes here.

This is a simple, manually configured driver board that can do micro-stepping and can be made by a kitchen table constructor. It is not meant to be small and there are no surface mount components used in it's design.

Based on the Toshiba TB6560AHQ stepper driver IC it features 2.5A continuous and 3A peak drive with advanced current control features. Plenty for any model of RepRap.

The second part of this project is to convert the design to a SPI based programmable controller with step and direction signals that allows full 5D driving from a micro-controller with a limited pin count. (28Pin Arduino)

But first to build a few of the manual boards and evaluate them on my Huxley build.

Thats a realy usefull PCB design for home use not only for RepRap but many other projects!
I will definatly be making a couple for one of my other projects that require the higher current drive.

Thank you..
Is this driver compatible with pololu or RAMPS style boards? I assume it would need to be wired in rather than plugged in due to footprint, but are the pins basically compatible?

Would this be compatible with a RAMPS or Pololu board as long as the pins were wired to the right places? I assume the footprint is different, but might be wired in point to point.
