Product Introduction:1. This module is a pulse generating module, which supplies as a signal for stepper drivers. To control the stepper motor, it must be equipped with the driver.2. Easy controller + stepper driver + stepper motor + DC power composed a simple control platform.3. The controller consists of 3 kinds of frequency signal, including 5.4k-160khz, 540-16.6khz, 80-2.4khz, which can be chose by skipping stitch.4. Support generating a pulse and PWM signal ,support skipping stitch choice.5. Frequency measurement: the two ports of PUL and common-cathode (or common anode) can be measured .Different stepping motor driver different port sign, but same functionEN=ENA=FREE   EnablePUL=PULS=CLK  PulseDIR=CW=CWW    DirectionCommon anode connection (connect with B)EN+  PUL+   DIR+  all link together  to common  anode portEN- connect to    ENPUL- connect to  CLKDIR- connect to   DIRCommon cathode connection (connect with B)EN-  PUL-   DIR- all link together  to  common cathode portEN+  connect to    ENPUL+ connect to  CLKDIR+ connect to   DIRPackage includes:1 x Stepper Motor Driving Controller
