Features

I like retro-computers. Most of the retro-computer projects use PS/2 keyboards due to the ease of interfacing. I found panel mount connectors nice but hard to find and somewhat expensive. This card works well for the need.

  • PS/2 keyboard/mouse interface
  • Two PS/2 connectors
  • Power options for 3.3V or 5V
    • 3.3V/5V Host and 3.3V/5V Keyboard/Mouse
    • Option for bi-directional level translator TXS0104EDR
  • Bypass resistors for direct connection

Connectors

J1 - PS/2 #1

  • Standard PS/2 Mini-DIN female connector
  • Color codes Purple = Keyboard

J2 - PS/2 #2

  • Standard PS/2 Mini-DIN female connector
  • Color codes Green = Mouse

J3 - Host connection

  • PWR1 is the power to the PS/2 #1, #2 connectors
  • +3.3V connections are only needed when the TXS0104 translator is installed
