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
Components on bottom PCB side for better heat emission, further infos here
Trinamic stepper motor driver (chopper drive / constant current drive)
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
