1. Overview
This document guides users how to use the SK202
modules transmits Gigabit Ethernet signals at a distance of several centimeters in a
contactless way. SK202 opens a new scene for network connection applications. This
module integrates a network PHY chip and
transceiver chip, which can be simply connected to the existing Ethernet
network cable. Please note is that both
