Ugreen-OS Full size Wireless Keyboard / K331
The UGREEN K331 (item 65734) is a full-size 2.4GHz wireless keyboard with 104 keys. It connects through a small USB receiver that you plug into a free USB port on your computer, and it works at up to 10 m from the receiver.

Full-size 104-key layout: The keyboard has a full 104-key layout with a number pad and an Fn key. Typing numbers, shortcuts and long texts feels the same as on a standard desktop keyboard.
2.4GHz wireless up to 10 m: Plug the USB receiver into your computer and the keyboard connects automatically, with no cable on the desk. The wireless range of up to 10 m also lets you type from a distance.
Power saving and low-battery warning: After 15 seconds without use, the keyboard switches to an energy-saving mode and wakes up as soon as you press any key. A low-battery indicator warns you in advance when it is time to change the batteries.

ABS body with tilt feet: The body is made of ABS plastic for impact and wear resistance. Two feet underneath let you raise the back of the keyboard to a more comfortable typing angle.
Works with
Computers running Windows, macOS or Linux with a free USB port for the receiver.
