  • For those who asked, here is a quadrature encoder tutorial I found. I hope this is what you were asking about: http://letsmakerobots.com/node/24031

  • Is Pololu the only place selling expansion plates for this chassis? Can you guys make and sell some? The only thing keeping me from buying one is that I’ll quickly run out of room for expansion. Thanks

  • Worked perfectly for me the first time using dfu-util v5 on Ubuntu, also.

    In Windows Vista, fail.

  • I see you have them now. This thing is fairly large. Do you think it would be possible and/or relatively easy to mount on a large robot? (The robot will be based on a modified Peg Perego Truck (think, Power Wheels), so about the size of one of those children’s electric ride-on vehicles). Thanks.

  • Is that the antenna connector there on the module? Which SparkFun antenna(s) are compatible with it?

  • So as a PIC-based component, is this motor controller not compatible with Arduino? It shouldn’t matter, as long as you send it the correct signals, right?
