SilentStepStick

The Silent-Step-Stick is a Stepper Motor Driver Board for 2-Phase Motors based on a Trinamic TMC 2100, Trinamic TMC 2130 or Trinamic TMC 2208.

Hardware compatible with StepStick and Pololu A4988
Trinamic stepper motor driver (chopper drive / constant current drive)
Components on bottom PCB side for better heat emission, further infos here
Automatic standby current reduction
microPlyer - microstep interpolator for increased smoothness of microstepping
stealthChop - for quiet operation and smooth motion
spreadCycle - highly dynamic motor control chopper
Extra features of TMC2130:
- SPI configuration interface (up to 4MHz)
- up to 256 native microsteps (without interpolation)
- coolStep - current control for energy savings
- stallGuard2 - sensorless motor load detection
- dcStep - load dependent speed control
- Automatic stealthChop and spreadCycle switchover depending on velocity
Extra features of TMC2208:
- UART configuration interface (9600...500k Baud)
- up to 256 native microsteps (without interpolation)
- stealthChop2 - faster motor acceleration/deceleration than stealthChop
- Automatic stealthChop and spreadCycle switchover depending on velocity
