If you can make a board with headers for pololu and compatible stepper drivers like StepSticks, that can open up a wide range of options. The pololu and ones based on them typically have a 1.2 amp motor limit, can be pushed to 2 amp by using heatsinks and blowing air on them. There are others which are pin compatible and use higher amperage chips with an improved PCB design to enhance heat removal. To see what can be done with such a design, search for RAMPS. IIRC there's at least two RAMPS to Beagle adapter boards. RAMPS originally being designed for Arduino, those RAMPS adapters also enable using some other Arduino boards on the Beagle. RAMPS = RepRap Arduino Mega Pololu Shield A pure Beagle 'port' would be RepRap Beagle Mega Pololu Cape or RBMPC which just isn't anything pronounceable. ;) ------------------------------------------------------------------------------ DreamFactory - Open Source REST & JSON Services for HTML5 & Native Apps OAuth, Users, Roles, SQL, NoSQL, BLOB Storage and External API Access Free app hosting.
