1. Supports 12V/24V power supply, adapting to various stepper motor drive requirements. 2. Enables forward and reverse rotation control, flexibly handling complex situations. 3. Integrated speed control module for precise motor speed adjustment. 4. Outputs PWM pulse signals with high stability and fast response. 5. Comprehensive product features, suitable for various automation control scenarios. 1. This module is a pulse generator that provides control signals to the stepper driver. To control a stepper motor, a driver is required. 2. This simple controller, stepper motor driver, stepper motor, and DC power supply form a simple control platform. 3. Frequency measurement: PUL and common cathode. Different stepper drivers may be labeled differently. EN = = Free Enable PUL = PULS = CLK Pulse DIR = CW = Direction Common Anode Connection Method (A) Connect EN+, PUL+, and DIR+ to the common anode terminal Connect EN- to EN Connect PUL- to CLK Connect DIR- to DIR Common Cathode Connection Method (B) Connect EN-, PUL-, and DIR- to the common cathode terminal Connect EN+ to EN Connect PUL+ to CLK Connect DIR+ to DIR Color: As Shown Material: PCB Package Contents: 1 x Forward and reverse controller speed control module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
