Odseven PS/2 Keyboard+Mouse to USB Adapter for Raspberry Pi
This is a nice solution to wanting to use PS/2 devices (such as our capacitive touch pad or mag-stripe readers). It's also handy if you want to connect a keyboard and mouse to a Raspberry Pi or Beagle Bone without taking up two USB ports. Inside is a full translation chip - a small USB micro controller that will translate the PS/2 into "USB Keyboard" and "USB Mouse"
We tested this with a Pi, Bone, Linux, Windows and Mac desktop computer and they all worked flawlessly.
