The BeBoPr board is available now and has support for both the Pololu drivers common in the 3D printer world and a header to drive out-board stepper drivers with a more "oomph". From the BeBoPr maunal: J5 – all stepper signals are present on this connector. It connects directly to the 15 pin sub-D connector of a TB6560-4V5 3A stepper driver board sold on e-Bay. There's also the Replicape, but AFAIK it's on-board stepper driver only (Pololu class, but using TI driver chips). There's nothing I'm aware of yet that works for analog servos, but it should be possible, at least for a few channels (the CPU has 3 hardware encoder inputs, and the PRU could support more in "software" at lower pulse rates). -- Charles Steinkuehler char...@steinkuehler.net ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
