Welch Keyboard Studio

Public docs hub on welchsoftware.net. The desktop app covers EVision boards (Redragon K550/K552/K556/K580 Kato and cousins) and Das Keyboard Q models. Source stays in a private GitHub repo — visitors use this domain, not GitHub.

Compatibility quick check

EVision — Device Manager shows a collection like HID\VID_…&UP:FF1C (usage page 0xFF1C).
Das Q — Metadot / Das VID 24F0 with the RGB System Control collection (usage page 0x01, usage 0x80).
Unknown boards on those VIDs can still open as experimental in the Boards tab.

Safety

Every accepted EVision write commits to on-board flash.
Leave dry run on until you confirm the device.
Use Apply deliberately — the app is a configurator, not a streaming engine.
