Feature: 1. This module is pulse generation module, supply stepper driver as a , to control stepping motor, also must match the drive.2. The simple controller + stepper driver + stepper motor, dc power can be composed of a set of simple control platform. 3. The controller has high 5.4 k 540 - in - 160 KHZ, 16.6 KHZ, low on a total of 3 80-2.4 KHZ frequency can be used to jump needle selection. 4. Can produce pulse as well as PWM , cand an choose jumper. 5. Frequency measurement: can measure both PUL and coyin (or coyang) ports. Specification: Condition: 100% Brand New Item Type: Stepper Motor Drive Controller Material: Metal Coloe: As Pictures Shown Out of sync motor driver port tag is different but the same function EN = ENA = can make PUL = PULS = CLK pulse DIR = the CW = CWW direction Yang connection (B) EN + PUL + DIR + together received a total of anode side. Meet EN EN - PUL - answer the CLK DIR - meet DIR A total of Yin connection (B) EN - PUL - DIR - together received a total of cathode . EN + meet EN PUL + answer the CLK DIR + meet DIR Package List: 1 x Stepper Motor Drive Controller2 x Screw Gasket |
