SK8702 - FlexPoint™ PS/2 Pointing Stick Mouse Module

Overview

The SK8702 pointing stick module is a cost-effective, space-saving PS/2 mouse device deploying a Sprintek SK7102 pointing stick controller. Typically, consuming 650uA in idle state, the SK8702 is ideal for battery-operated systems.

Deploying CellMute technology to filter the wireless EMI noise from cellular phones and wireless networks, the SK8702 modules can work quietly in wireless environment.

The SK8702 module partially implements the Lenovo TrackPoint® extended command protocol and can work with Lenovo TrackPoint® device drivers directly.
