Yesterday we manufactured a batch stepper motor drivers, this ones are based on a brand new Trinamic chip.
The design is compatible to the popular StepSticks or Pololu A4988, but with some improvements.
We will make a Google hangout in the next 1-2 weeks, to show the features.
@Anton_Fosselius , from what I’m reading 2.5A peak current, 1.2A RMS, looks like they take 16 microstep, and interpolate it to be 256 microstepping. They have a feature called “stealthchop” which apparently makes them run much quieter than a standard A4988.
Looks like they have posted a video of someone who has the driver on their X axis, but the regular A4988s on their Y/Z axis here: http://youtu.be/mJmg0iRHX8s and if the sound is as quiet as I’m being led to believe, I am VERY interested in these.
