PS/2 Click Board
Introduce keyboard and mouse connectivity to the device with this cost-effective solution - the PS/2 Click Board.
This add-on board includes a standard 6-pin Mini-DIN PS/2 connector, a MikroBUS pinout, and a power indicator LED. PS/2 click features a PS/2 port for connecting a keyboard or mouse to the target device. Although, superseded by USB, it is still used as an alternative to the USB connector. It is well-suited for connecting vintage keyboards and mice or certain high-end keyboards for gamers due to its full N-key rollover functionality. PS/2 click communicates with your target board through MikroBUS RST (data) and CS (clock) pins. It is designed to use a 5V power supply only.

PS/2 click has a PS/2-style 6 pin mini-DIN connector used for connecting some keyboards and mice to a PC compatible computer system. It was first introduced by IBM way back in 1987. It works on a serial, synchronous and bidirectional communication protocol.
Full N-Key Rollover
PS/2 click is used in certain high-end keyboards, especially for gamer keyboards as it supports n-key rollover. This means that each key is scanned entirely independently by the keyboard hardware, and thus, allowing the high-end keyboards to handle any number of simultaneous keystrokes. .
Why PS/2 over USB?
Though superseded by USB, PS/2 connectors are still used. The PS/2 connected keyboards are faster, and have slightly shorter effective scan intervals than their USB counterparts. PS/2 supports full n-key rollover, whereas USB keyboards can handle typically two to six keys at a time.
