We’re really happy to be carrying the latest, top-of-the-line RepRap electronics which we use to drive our MakerBots. These boards were developed by me (Zach Hoeken) as part of my volunteer work for the RepRap Research Foundation. As always, the designs are 100% open and free. You can hit up the files on Thingiverse, you can read the blog entry introducing the design on the RepRap Blog, or you can skip straight to the wiki page for full-on documentation. Oh yeah, and we sell them in our online store if you want to get a hold of one. We’re in the process of getting these boards fully assembled (a first for us) and this will probably happen in the next month or two if you don’t feel like doing SMT soldering.
