This module is a pulse know-how module and materials a stepper driver as a signal. To management the , it needs to be geared up with a driver. This clear-cut controller + stepper driver + + DC calories transport can variety a straightforward management platform.(Only the controller is included.) The controller has a complete of 3 varieties of frequency signals: excessive 5, medium 540-16, and low 80-2, which are with a jumper. It can generate pulse signal and PWM signal, and it may be by means of means of jumper. Frequency measurement: You can measure PUL and customary cathode (or ordinary anode) two ports. Power Input: 8-24V Frequency Signals: 5,540-16,80-2 Colour:black Material:PCB board Package Contents: 1 x Controller Only the above equipment content, diversified products usually are not included. Note: Light and varied exhibits could cause the colour of the thing within the photo a little bit varied from the real thing. The measurement allowed error is +/- 1-3cm.
