I am eagerly waiting for my Hadron Kit like everybody and I would like to give a heads up for an alternative electronics for those on the fence on what controller to get. I designed this to be a low cost board based on the Sanguinololu with some of the features found on the RAMPS board, like fan output, SDRAMPS port plus other great features. Im doing a pre order right now for those interested. Its slim 2x4 size allows itself to be mounted nicely on the back of the Hadron and the Blue PCB should blend well too. Its fully assembled, well almost except for the connectors as you are given both a vertical and a right angle set. Board has been tested for weeks by select individuals.
Anyway, please give it a look. It might just be what your Ordbot needs(and have some $S to spare).
