The STD-503 is a 2.4 GHz transceiver that uses Direct Sequence Spread Spectrum (DSSS) modulation and true diversity circuit, enabling reliable communications even in the congested 2.4 GHz band. The transceiver complies with the European EN300 440, U.S FCC Part 15.247, Canadian IC RSS-210 and Japanese ARIB STD-T66 standards, making it ready for the global market. The STD-503 is available in a small compact shield casing designed for industrial applications such as telemetry systems and industrial telecontrol. This low power module's configuration can be set easily via the UART interface using dedicated commands.
