Mighty keyboard and macropad

MA21 was designed to fulfill the heavy needs of number pad for accounting job or Chinese typing (九方輸入法). Unlike traditional fullsize keyboards, MA21 works as an individual numpad and can be put anywhere at your comfort.

Even if you are not a heavy number pad user, you can also benefit from MA21 with its macros. You can assign a long keystring into MA21 and call it out with one punch! Tasks like copy and paste, calling a certain software, typing a repetitive sentence or code can now be easy.

Stunning lighting effect and design

The RGB LEDs under the circuit board are programmable to give millions of colours defined by 6-digit hex code (like #FFFFFF for white). Effects like fading and flow are also available. The edge of the aluminium case is designed to have a lighting bar to show the beautiful colours of the RGB LEDs.
