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.

Mechanical Keys, Gateron Switch of Your Choice

Keyboard Key Switch Mechanisms

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

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 is what you can program:

• Set a key to send any key on PC keyboard, including modifiers such as Ctrl, ❖ Window, F12, PrintScreen, NumLock, 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)

Paired Model

Also available is a paired set model. I don't have experience with it.
