I'm trying to work out whether or not the Silent2209 has external sense resistors on board and if so, what those sense resistors are. Is there a more detailed schematic available for the Silent2209? Or perhaps someone knows already if and what external sense resistors are used?
The site for the Silent2209 briefly mentions:
The maximum settable motor current is 1.77A RMS (0.11Ohm sense resistors), but the SilentStepSticks can only be used up to 1.2A RMS.
Does this mean that there's a 0.11Ohm sense resistor on each of the coils?
Thanks in advance for your time!
