INTRODUCTION

SR24NP module is a highly- integrated, single-chip, 2.4G wireless transceiver. It is equiped with

two antennas which can overcome the disadvantages of the single directional antenna as well as

enhance signal stability and transmission distance. It also has two serial ports to connect with

corresponding serial devices. it can be flexibly configured for RF front-end transmitter or receiver

in the model aircraft system. Its transmitter power can be set from 0dB to 4.5dBm by software.
