Single Sided RepRap Stepper Driver

I'm experimenting with a single sided version of the makerbot / reprap stepper driver board.

V1 - based on Stepper driver 3.0

Original makerbot/reprap stepper driver 3.0 board, with connectors and through hole components flipped to the other side.
Vias moved and straightened - easier to make as wire links.

So far, completely untested :-)

V2 - based on Stepper driver 2.3

Original makerbot/reprap stepper driver 2.3 board, connectors flipped to other side. Vias moved and straightened, RJ45 ports (Makerbot duplicate max/min connectors) removed - using the original 3-pin connectors instead.

V3 - based on Stepper driver 2.3

As per version 2, some build modifications: Vias enlarged (more copper to solder to), vias/wire links repositioned, extra (2.54mm) molex header added for stepper motor because I bought loads of them.
Note that the IDC I think is the wrong way round from the 'real' 2.3 stepper driver board. Check the pin-outs.
