Depending on your requirement there are a number of potential motor control interface options which can offer simple or more in depth control as required.
Potentiometers and buttons/switches are the simplest form of user interface which will work with the Zikodrive range of stepper motor controllers and brushless ESCs. In combination with the programmability of all of our controllers these can be set up to operate in pretty much whatever way you might want. Typical methods usually involve having a pot as a speed control and buttons for stop/go and forward/reverse but we have sometimes added additional controls for features such as current control and microstepping. The simplest thing to do if you have something slightly more customised in mind is to give us a call or an email and we will tell you what we can do.
