Kelvin UI Board for Epos 300 Controller

The UI board is the internal circuit board that drives the Epos 300 controller's touch screen and button inputs, sold as a stand-alone service part for repair rather than replacing the whole controller. It mounts behind the top enclosure with the plastic screws Kelvin uses throughout the Epos controller assembly.

This part is intended for an existing Epos 300 controller that needs its control electronics serviced, not for building a new controller from scratch.
