SIKAI Keypad Lab

Open Keypad Lab and configure your keypad →

A browser-based configurator for the SIKAI two-key RGB keypad. It uses WebHID to read and update onboard key assignments and supported lighting settings.

Tired of downloading and installing another application just to configure a two-key keypad? So was I. Keypad Lab lets you configure it directly from a supported browser.

This project was built and tested for the SIKAI two-key Copy/Paste keypad, which is also available from this Shopee listing. If you purchased the same model, give it a try.
