Functionality

Main Board

The main functionality of the main board is to notify the RetroTink 4K of the change and trigger an SVS profile change via serial commands when the selected input on the gSCARTsw changes. This is a hard-coded automated process and does not require user interference.

Please refer to the RetroTink 4K Wiki for details on how to set up the SVS profiles.

Keypad

The keypad has 8 keys, corresponding to each of the inputs on a gSCARTsw. An OLED screen and 16 addressable RGB LEDs provide visual feedback of the operation state.

A firm press on a key will trigger a corresponding input change, as well as notifying the RetroTink 4K with an SVS profile change command.

If 1/SHIFT is held, you can use the various functions marked below each of the input keys.

Holding an input key for longer than 2 seconds will trigger input icon customization. You will be able to choose an icon for the corresponding input for better recognition.
