PS2X49 REV 1 P858-720PX.jpg

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 TXS0104
  • Bypass resistors for direct connection
