The STD-503 2.4-GHz radio transceiver module enables the simple embedding of wireless capabilities in industrial remote control equipment. Suitable for worldwide apps, the module suits industrial applications that must have stable and reliable communication for up to 300 yards with battery operation. To ensure highly reliable radio communication in the congested 2.4 GHz ISM band, the module uses highly noise-resistant direct-sequence spread spectrum (DSSS) modulation, as well as a true diversity receiver design that employs two antennas, each with its own receiving circuit, thus preventing signal dropout due to multi-path fading. The data interface is transparent, enabling users with proprietary protocols to use them without modification. Measuring 1.6" x 1.15" x 0.22", the STD-503 is 50% smaller than its predecessor the STD-502-R. Additionally, the STD-503 now allows channel switching according to a preset channel plan via pin selection. Up to 20 frequency channels can be saved in the plan.
