So, I'm working on updating the Rambo pins.h documentation for the default Marlin Firmware.

So far I have added servo support with the 4 available pin optionsand documented the Fan pins

Those have been pull requested at this point.

After the fact i thought about adding a define for #AUTO_FAN

can anyone think of anything else?

I realize that most of the newer people wont know, for that matter i'm pretty new myself and figuring it out but i have come to realize that RAMBo support is pretty minimal, unless you speak directly with reprapelectro. So I thought i would help the community as best i could by documenting things better.
