Abstract: Application in sensor networks is becoming more and more complicated as the intensive study in recent years, which challenges the traditional mote platform design. To solve this problem, this paper proposes the design of a general mote platform called NPUMOTE3, whose process speed, storage capacity and transmission distance are improved, meanwhile, it is easy to interconnect with peripheral devices and develop new applications, satisfies different requirements in research, education and production.
