Koolertron Keyboard

USA is thriving with crowd funded fancy keyboards that will become available in year 3000, or DIY keyboards that take a life-time to build.

Meanwhile in China, sound ergonomic keyboards, are a dime a dozen, and 5 times cheaper, and you can buy it NOW. Here's one of them.

The LY092 Mini Keyboard/keypad came out in 2017.

Plug and Play, Works in Linux and Mac

No software driver needed. Plug and Play. Works in Linux and Mac.

If you didn't program the keys, keys are their default action.

Can 2 Keypads Work as Full Keyboard?

If you buy 2 independent ones, and connect both to the computer. Then, on a Mac, the modifier does not work with the other pad. You press shift on left, and press a letter key on the right, doesn't work. However, it works this way on linux and Microsoft Windows.

Programable Keys

Sample use. (available in English, Chinese, Japanese)

The software to program keys is for Microsoft Windows only. (it does have English and Chinese versions.)

Once the keys are programed, they are in the keyboard's memory. You can plug the keyboard in any other machine, Mac or Linux or Microsoft Windows, and it'll work right away.

Here's what you can program:

• Set a key to send any key on PC keyboard, including modifiers such as Ctrl, ❖ Window, F12, Print Screen, Num Lock, or number pad keys. Any that appears on a full sized PC keyboard.

You can also use a HID key code. (that's the keycode used in USB)

• Set a key to send any key combination. That is, ❖ Window, Ctrl, Alt Shift, or combination of them, with another key on PC keyboard.

• Set a key to send mouse click, including {left, middle, right} buttons. You can also set a key to move mouse by {x,y} pixels.

• Set a key to send a Fn1 or Fn2 key combination with another normal key. (the fn are special modifier keys.) I haven't used this feature.

• “burst keys” → Set a key to type a sequence of 3 keys.

• “round robin keys” → Set a key to type a cycle of 3 keys. That is, first press, type A, second press types B, third press types C. The A B C can be any PC keyboard keys.

• “continue key”. → Set a key X to send another pc key continuously. Press X again to stop.

• “jitter key” → Set a key to type another key, emulating user repeatedly hitting the key as fast as possible. e.g. the fire button in gaming. 20 key singles per second.

• Control backlit. (only for those with backlit models.)

• Disable a key.
