SKU EF There are USB boards the Smoothstepper is one that can actually generate step and direction pulses suitable for CNC, but these are more properly motion controllers than breakout boards.

See the section below for more. There are a number of keyboard emulators out there, but I believe the most popular are Pokeys and the iPac, which is sold Ultimarc. The basic iPac provides an additional 28 inputs, which is substantial. There is an enhanced version th at allows 56 inputs.

For example, I would tend to avoid using them with joysticks. But they are a good way to pick up all the extra buttons on your control panel. At the high end of the breakout board spectrum are the motion controllers. They are so high their makers probably object to comparing them to breakout boards. I only do so because they replace the breakout boar d. Mach3 works with several, including the Smoothstepper probably the most popular as I write this , the Galil, and others.

These boards offer a tremendous performance upgrade over parallel boards and the like. I have a Smoothstepper, which has worked great. Before taking any final steps on a motion controller for your own project, I highly recommend you spend a lot of time getting acquainted with the various online communities associated with your controller software and the motion board in question.

You may also want to read about how to set up a Smoothstepper for my servo-based mill. This is especially true for the higher powered servos on a larger machine. What about spindle speed control? Mach 3, on the other hand, puts out digital pulses, so you need a board to convert from the digital world of Mach 3 on one output pin to the analog realm expected by the VFD.

Hopefully the board will isolate the sensitive digital electronics from any potential for line voltage s to get back into the digital side as well. The interface board was designed to be simple and used for initial experimentation.

KiCad source files are provided so that the design can be modified if needed. As the circuit diagram shows, the design is very simple. Surface mount parts were used for the MAX RS chip and n capacitors as can be seen in the photo below. These parts can easily be changed to through-hole parts using the KiCad source files provided if desired. A surface mount MAX was chosen as they are generally cheaper and more easily available than the through-hole mounting equivalents.

The surface mount parts are not difficult to solder and should be soldered first.
