As USPS, FedEx and UPS have suspended mail service to Russia and Ukraine we cannot currently ship to these two countries. Thank you for your understanding.

Due to the global chip crisis KStep is currently out of stock. We are working hard to correct the situation.

You will find that our control boards offer exceptional value when compared to the competition. Especially when you consider that our software and subsequent updates are completely free. Combine that with a satisfied user base and you can have confidence that your purchase is a solid investment.
