The STD-502-R 2.4 GHz transceiver is designed with direct sequence spread spectrum of DSSS modulation. It also has a real diversity circuit enables a reliable communications even in the congested 2.4 GHz band. This tool relies with the European ETSI EN 300440, U.S. FCC Part 15.247 standards and Japanese ARIB STD-T66 standard. This device is built with a minimal power consumption. It consist of battery operation that provides the demand performance, with long range is needed for applications. It also utilizes a transparent data interface to communicate using protocols. This tool contains modules which can be set easily via the UART interface using dedicated commands. This device also has circuit design enhanced an onboard ASIC consisting SS correlator.
