There are several versions of this keyboard available.
- Black, LED Backlit
There are also at least two different US ANSI layouts. The layout pictured below has the following keys in the far-right column: Switch Lock, Pause/Print Screen, Page Up/Home, Page Down/End, Delete/Insert, and right arrow. The non-backlit model alphanumeric legends are laser etched with gold-coloured text. The newer layout changed the far-right column to: Delete/Switch (Lock), Home, Page Up, Page Down, End, and right arrow. Insert is moved to the Fn layer of F12. The non-backlit model alphanumeric legends of this version have white text. Additional changes exist besides those in the far-right column, but that column saw the majority of the alterations. The change appears to have been made by February 2012.
The front printing is split into several colours: sky blue for num lock and the integrated numeric keypad; magenta for insert, Windows key lock, and the media controls; white for scroll lock, and green for switch lock, which swaps caps lock and control keys (with a dedicated LED). The modifier keys use only text for their legends. Status LEDs are provided by windowed keycaps.
The space bar also sports a Noppoo branding in form of the company logo and text.
The laser-etched keys of the original version are very susceptible to staining, as illustrated below.
This keyboard features N-Key Rollover over USB. It achieves this by exposing two separate keyboard interfaces over the USB port, which works similarly to as if there had been a USB hub with two keyboards attached.
The Noppoo doesn't work on Apple macOS and iOS without workarounds:
- Setting the keyboard in PS/2 mode and use a PS/2-to-USB converter.
- Use thefloweringash's Kernel Extension IOUSBHIDDriverDescriptorOverride and KeyRemap4MacBook.
The technical reasons for the problems with Apple products are two: 1. It uses a report format which Apple's parser has a problem with. 2. It supports only low-speed USB, which has a report size limit of 8 bytes. To get around that limit for NKRO, it uses two HID interfaces but of which only one carries the modifiers, and Apple's HID class driver does not combine modifiers from different keyboards.

The following pictures date from 2011, prior to the layout changeover in 2011 or early 2012. This version used natural colour laser-etched legends.
