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
