Solnoi Electronics EasyDriver Stepper Motor Driver V44 A3967 Micro Controller Board Electronic Hobby Kit

The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). It requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. Ms1 and MS2 is a stepping motor subdivision resolution selection logic input port; Dir is the choosing of motor operation; Reset to reset the chip initializer and block all external output; Step pulse input ports; Out1a, out1b, out2a, and out2b into two h bridge on the output port; Enable to enable; Sleep sleep mode; Sense1, sense2 for h-bridge current detecting resistors; REF is the reference voltage; GND for logic and power; RC1, RC2 for the h-bridge is a fixed deadline for analog inputs.
