E-Field Serial Touch Pad

The MC33794-based E-Field Serial Touch Pad is designed around the MC68HC908JK3 microcontroller. The touch pad connects through a PC’s serial port using the same protocol used by serial mice. Commands are performed by moving your fingertip around the system’s pads, which are aluminum. Clicking is performed by gently tapping the middle pad.
