Stable serial communication at 2.4GHz through Spectrum Direct Sequence Spread Spectrum (DSSS) and True Diversity reception embedded wireless module.
The STD-503 is a compact, embedded wireless transceiver module designed for industrial applications that require stability and reliability, operating in the 2.4GHz ISM band available worldwide. It operates on battery power and achieves wireless communication with a line-of-sight range of 300 meters. To ensure reliable wireless communication in the 2.4GHz band, it features a spectrum direct sequence spread spectrum (DSSS) method that excels in noise resistance, along with a true diversity reception function that prevents signal drop due to multipath fading. Additionally, the transparent data input/output interface allows users with their own communication protocols to use it without changing their protocols. It is a highly flexible interface that can transmit continuous LOW or HIGH signals without restrictions. The communication settings for the STD-503 can be configured via serial communication (UART). 【Features】 ■ Spectrum Direct Sequence Spread Spectrum (DSSS) ■ Transparent Data Input/Output Interface (Clock Synchronized) ■ True Diversity Reception
