... Mouse Sensor Kit (#28560) The Parallax Mouse Sensor is a module in kit form which, when assembled, provides the tracking functions of an optical mouse. The two-wire serial interface is directly compatible with the Parallax BASIC ® Stamp 2 family, the Parallax Propeller™, and other microcontrollers. ...

... The three-wire Propeller circuitry is a little more complicated than that of the BASIC Stamp. This is because the Propeller outputs do not rise high enough to turn off a PNP transistor powered from +5V. Therefore, an additional transistor is required to do the job.
