2.4 GHz transceiver module STD-503

radioDSSSremote control

The STD-503 is a 2.4 GHz transceiver enclosed in a small compact shield casing designed for industrial applications. The transceiver uses Direct Sequence Spread Spectrum (DSSS) modulation and true diversity circuit, enabling reliable communications even in the congested 2.4 GHz band. The STD-503 complies with the European EN300 440, U.S FCC Part 15.247, Canadian ISED RSS-210 and Japanese ARIB STD-T66, making it ready for the global market. Low power consumption and battery operation give the STD-503 the performance demanded for applications where long range and reliability are required. The transceiver uses a transparent data interface to enable users to communicate using their own protocols. The module's configuration can be set easily via the UART interface using dedicated commands. *Circuit Design developed an onboard ASIC containing SS correlator (a key part of spread spectrum communication). This ensures long term supply for industrial applications Features - CE, FCC, ISED and ARIB conformity certification - Uses direct sequence spread spectrum (DSSS) modulation - Channel stepping option controlled via CHC pin - A true diversity receiver ( two built-in receiver circuits) - Module settings using dedicated commands - Data communication uses a transparent interface - Low power operation - 77 channels - Range 300m LOS - Onboard temperature sensor
