SMD8A

High performance microstepping driver. capable of driving size NEMA17, NEMA23, NEMA34and NEMA42 stepper motors. Motor currents are selectable from 1 to 8.0 Amps by dil switch. 6 microstepping resolutions from 1 to 32 microsteps per step. Ideal in the applications where speed and the power are an important factor. Anti-resonance algorithm insures smooth, quiet operation.
