Description

The controller is a component of the keyboard or a mouse replacement that tells the computer / PC which key of the keyboard matrix is pressed or in which direction a mouse is being moved.
The controller also regulates the switching of the status LEDs, such as the shift lock, NUM lock and scroll lock.
Controllers differ among other things by:
Different exits
Different controllers support different interfaces. In the case of keyboards, these are the AT (PS / 2) or serial interfaces. For mouse input devices, these are PS / 2 or serial.
Different entrances
Keyboards are used as a matrix, trackballs and other mice, on the other hand, are connected to the controller via the quadrature.
Most of the controllers we manufacture and sell can be customized. In this way, entire sequences of letters can be programmed onto a specific key of a matrix of a keyboard. With mouse controllers, on the other hand, you can adjust the transfer rate, among other things. Just ask us about the right controller for your application.
