PRO Chopper Driver Board

HobbyCNC Pro Driver Board

The HobbyCNC PRO Chopper Driver board is one of the more popular stepper controller boards for the hobby CNC market. Good for use on routers, lathes, mills, PCB drillers, engravers — the possibilities are endless.

I recently had the opportunity to build up one of the boards from the kit they offer for a friend who lacked the skills to solder up the system. Assembly was straight forward and a novice builder should be able to complete the board assembly in less than 90 minutes.

The instructions which come with the unit are very simplistic, but they do give you the basic information to complete the assembly of a board. It is important to follow the instructions carefully as there are a couple of parts and positions on the board which can easily be confused if you do not watch what you are doing.

As you follow through the guide, you will be instructed to insert the necessary components in to the board. After inserting them, you can confirm the positions by matching up our pictorial display and also as a final confirmation the instructions received with your kit. In each step, once you are sure you have positioned the components to the their correct locations, you can proceed to solder the components into place.

Presented on the following pages are the step-by-step process we took to build up the board — and yes, it worked perfectly the first time we powered it up on a three-axis system.
