Welcome to Dynomotion

Thanks for visiting. We make control boards designed to develop, automate, and enable interactive objects and mechanisms. We are excited to be a part of a revolution in the controls industry that is pushing down the price and increasing the quality of control boards that are available to the professional and the hobbyist alike. Our strategy is to offer extreme flexibility, capability, sophistication and accuracy for a variety of applications on a single board, and a suite of boards, for a low price.

Choose Dynomotion's products because...

Our boards offer exceptional capabilities and rock-solid performance. The control algorithms implemented by our software are state-of-the-art and you have the capability to program the board in native C programming language and use G-code for CNC applications using our free KmotionCNC software. Our software also offers full PID control with an easy to use tuning process.

We are passionate about control boards and equally passionate about serving our customers. In over 20 years of business, we have sold to thousands of satisfied customers in over 40 countries. We feel strongly that we offer some of the best control products on the market, but you don't have to take our word for it.
