Feature: 1. Provide Control Signal: This module is a pulse generation module that provides control signals to the stepper drive. 2. Simple Control Platform: This simple controller + stepper motor + stepper motor + DC power supply can form a simple control platform. 3. 3 Kinds of Low Frequency Signals: The controller has high 5.4k‑160khz, middle 540‑16.6khz, low 80‑2.4khz, a total of 3 low frequency signals can be used to select jumpers. 4. Basic Specifications: The controller module can generate pulse signals or PWM signals, with optional jumpers. 5. Measuring Frequency: This is a controller module whose measuring frequency is PUL and common cathode. Specification: Item Type: Stepper Motor Module Describe: 1. This module is a pulse generation module, which provides control signals to the stepper driver. In order to control the stepper motor, a driver must be equipped. 2. This simple controller + stepper motor + stepper motor + DC power supply can form a simple control platform. 3. The controller has 3 kinds of low frequency signals of high 5.4k-160khz, middle 540-16.6khz, and low 80-2.4khz, which can be used to select jumpers. 4. Can generate pulse signal or PWM signal, and can choose jumper. 5. Measuring Frequency: PUL and common cathode. Different stepper drives may be marked with different names EN = ENA = FREE Enabled PUL = PULS = CLK Pulse DIR = CW = CWW Direction. Package List: 1 x Relay Module
