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
Drive capability up to 3A (RMS) continuous coil current
Step/Dir interface with up to 256 microsteps
SPI interface for configuration
Motor supply voltage: 10…35V
Logic supply voltage: 3.3…5V
RSense: 0.075 Ohm
What is the difference between TMC5160 and TMC2130 SilentStepSticks?
TMC5160 SilentStepSticks have no standalone mode and no internal pull-up resistor on the CS/SS pin. (SPI configuration is always needed)
The direction is not inverted on TMC5160 SilentStepSticks.
The software configuration is mostly the same, except the motor current calculation is different.
TMC5160 SilentStepSticks have an improved stealthChop mode (stealthChop2) and a higher motor current rating.
On TMC5160 SilentStepStick v1.3 the CLK pin has to be connected to GND.
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
This version is not required to be wired. It is used on the F6 board. We will provide the wiring version for other boards. Please pay attention to our shop or our facebook.
