While our Evolution Analog circuit board provides high resolution and stability, if you want the very best accuracy and reliabilty possible with a sim-racing controller, the Evolution Digital circuit board will provide that. Optical Encoders provide more resolution than potentiometers and do not have the inherent wear factor that a potentiometer does, and thus will last indefinitely.

We offer 3 pre-configured Digital models, but if you want a different configuration you can either modify one of those that is closest to your needs, or else utilize this upgrade option with one of our pre-configured Evolution Analog models to arrive at the desired controller configuration. When figuring the price of the end controller, add the price of this upgrade, then subtract the cost of the pots that would be included in the Analog model. In addition, if the controller incorporates a clutch, you would need to add the price of an additional encoder (price is listed on the main product page).

NOTE: This is not the correct upgrade option to use if you already own a TSW controller and want to upgrade it to Optical Encoders. This option is for new controllers only.

We do not stock a large quantity of the Evolution Digital circuit boards, so the availability of this option is limited. You may want to check with us for availability before deciding on this option.
