The OpenSprints project has been around for a over a decade, and in that time Arduino (which is the brains of the project) has made some significant improvements in driver support. If you purchased a second hand OpenSprints system, or you purchased our system before December 2014 we insist that you upgrade your Arduino. Beware of clones, we recommend buying from the source.
