Summary
This motherboard was based on JohnnyR's pololu shield for the arduino mega... I designed it to be flatter (less vertical) but larger in footprint. It measures 4" x 6" in total. The design only stacks 2 boards deep. The Pololu drivers are beside the main arduino. And the design plans for active cooling. All the hot components are on the side seperate from the arduino, so that ducted cooling can be used.
In addition I have expanded out the capabilities. Increasing to 2 extruder controllers, and a heated bed driver. I've also added headers for an LCD and keypad, as well as an expansion port. Trying to max out the potential of the arduino mega, so that this board can easily be expanded in the future without starting over.
Also the board is hopefully designed so it can be printed with the mendel (the etch resist mask)
This page will be updated and fleshed out as I have more time, but there were some interested parties, so I thought I would get the initial info up.
