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. This simple controller, combined with a stepper motor and a DC power supply, forms a basic control platform. The controller supports three frequency ranges: high (5.4 kHz–160 kHz), medium (540 Hz–16.6 kHz), and low (80 Hz–2.4 kHz), selectable via jumper. It can generate either pulse signals or PWM signals, selected via jumper. Signal measurement points: PUL and common cathode. 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.
