Koolertron Keyboard
Koolertron Keyboard (LY092 Mini 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.
Each keypad has 44 to 48 keys, depending on model.
Single Handed Models

- By default, it is a full mini keyboard, with letter keys and number keys, but no modifiers keys, and missing some punctuation and symbols such as , @ ! ?.

Mechanical Keys, Gateron Switch of Your Choice
Works in Linux and Mac
Requires Microsoft Windows to program the keys. Otherwise, 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
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 is what you can program:
• Set a key to send any key on the keyboard, including modifiers such as Ctrl, ❖ Window, F12, PrintScreen, NumLock, or number pad keys. Any that appears on a full sized computer keyboard.
You can also use a HID key code. (that's the keycode used in USB)
- Set a key to send any key combination. Including combined with modifier ❖ Window, Ctrl, Alt Shift.
- 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 key.
- continue key. → Set a key X to send another 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. example: the fire button in gaming. 20 key singles per second.
- Disable a key.
Paired Model
Also available is a paired set model. I don't have experience with it.
