Stepper Motor Controller Module With / Without Digital Display Potentiometer Speed Regulation Direction Control For 42 57 Stepper Motor DIY Motion Control Project

OSC V1.0 Stepper Motor Pulse Signal Generator Controller Module

📌 Product Overview

The OSC V1.0 stepper motor controller module is a professional pulse‑generation board, which outputs control signals for external stepper motor drivers. It cannot drive stepper motors directly. A complete control system consists of this controller, stepper motor driver, stepper motor and DC power supply. The module supports two output signal types: pulse signal and PWM signal, selectable via jumper cap. Three frequency ranges are available by jumper setting: high frequency 5.4K‑160kHz, medium frequency 540‑16.6kHz, low frequency 80‑2.4kHz. Rotate the potentiometer to adjust output frequency / motor speed conveniently. It is equipped with physical switches for power on/off and forward/reverse direction switching. Terminal definition:

• EN = ENA/FREE, Enable signal
• PUL / CLK = PULS, Pulse signal
• DIR = CW / CCW, Direction signal Support common‑anode and common‑cathode wiring modes to match most stepper motor drivers on the market. Power supply range: DC 8‑24V. Compact PCB size with mounting holes for easy installation.

⚠ Important Usage Notice

This module only generates control pulse signals, it cannot directly drive stepper motors, external stepper driver is required. Please pay attention to power supply polarity during wiring, wrong polarity will damage the module. Please select proper frequency gear according to your driver specification. Kind reminder: If there are version differences or images not been updated, please refer to the actual product.
