Replicate Control Boatrd for 3D Printers

[EagleSeven]

There is plenty of room for a heat sink on the back of the board. There are thermal vias going
through the PCB leading the heat to the underside. For most printers, it should not be necessary
with heat sinks, only for heavy duty printers pushing the stepper controllers to the limits.
For extra cooling, a small fan (15x15mm) can also be mounted next to the ethernet connector
forming a wind tunnel if needed.

Thanks for Info !
I really like the small compact overall size and the connector design used.
Looking Good !
Are those 2, 3 & 4 pin female connectors available at someplace like Newark ?
