This module is a pulse generation module that supplies control signals to a stepper motor driver. To control a stepper motor, a compatible driver must be used. A simple control platform can be built using this controller, a stepper motor, and a DC power supply. The controller provides three selectable frequency ranges via jumper: high (5.4 kHz–160 kHz), medium (540 Hz–16.6 kHz), and low (80 Hz–2.4 kHz). It can generate either pulse signals or PWM signals, selected via jumper configuration. Signal measurement points: PUL and common cathode terminal. Signal definitions: EN = ENA = FREE (Enable) PUL = PULS = CLK (Pulse) DIR = CW = CCW (Direction) Common anode connection method (B): EN+, PUL+, DIR+ connected together to COM+. EN− connected to EN. PUL− connected to CLK. DIR− connected to DIR.
