Currently, our official website only offers QWERTY (ANSI) layout keyboards. Some distributors also provide DE-ISO layout keyboards for the Gem80 model. These specialized layouts are customized by our regional distributors based on local market needs and are exclusively sold through them. If there is significant demand from customers for additional layouts, our distributors will consider customizing and releasing corresponding versions.

Our wireless keyboard supports up to ​5 devices, but connections are not simultaneous. ​

• Wired Mode: Simply switch to wired mode and plug in the USB cable for immediate use.
• Wireless Mode:

1. Press and hold the designated shortcut key to pair with ​3 Bluetooth devices and ​1 2.4G device.
2. Use quick-press shortcuts to switch between paired devices effortlessly.

To ensure optimal precision, our magnetic switch keyboards are currently designed for wired operation only. We have no plans to release wireless versions at this time. We sincerely apologize for any inconvenience this may cause.

• Third-Party Compatibility: Most cross-shaped keycaps (QWERTY/ANSI layout) available on the market are compatible with our keyboards. ​
• NuPhy Keycaps on Other Keyboards: If your external keyboard supports cross-shaped keycaps, our keycaps can generally be installed on it.
