General Description

In RF keyboard system, that is divided into two parts (the transmitter and the receiver). The eKK6511 micro-controller is dedicated to a RF keyboard encoder for single channel RF transmitter module. The eKK6511 is scanning keyboard state, encode key data and rely on RF Tx module to transmit data.
