Although this colorful peripheral is termed a “programmable keyboard”, it doesn’t have key-binding or industrial shortcut key features; rather, the programmable function is the color LED backlights in the keys:

• any of seven colors (red, yellow, green, cyan, blue, magenta, white)
• rainbow effect, a gradually-changing gradation
• sparkle effect, where only pressed buttons light up
• slideshow effect, which automatically switches between four pre-programmed color schemes
• adjust brightness

without the use of any control software.

A control program (“sold separately, not by the manufacturers, downloadable from an overseas website after a credit card payment”) allows minute adjustment of the colors in 512 different hues, saving of more than four color schemes, and an additional random lighting effect along with the ones listed above. 19mm-pitch and 2.5mm-stroke membrane keys, 380 mm x 180 mm x 24 mm (15 in x 7 in x 0.95 in)and 793 g (28 oz). USB 1.1 and 2.0. The Luxeed U7 has a Japanese layout; if you want a regular English keyboard, look at the Luxeed U5.
