M200 UI Controller Board Replacement

The first few batches of Select Mini’s had an issue with the control dial. A UI Controller firmware update in June added some debouncing code to help but it did not completely eliminate the problem.

The newer version of the UI Controller board added a 74HC14 Hex Inverting Schmitt Trigger. This was added to enhance signal condition for control dial. The updated UI Controller boards started shipping sometime in August. The update made a noticeable difference while using the control dial. No more or at least reduced skipping back or jumpiness while cycling through the LCD menu. Complaints are still made even with the newer boards.
