433MHz 20dBm RS485 Wireless Modem

Unit dimensions: 74 × 24 × 16 mm (excl. antenna). Enclosure: hybrid plastic/metal construction for EMI resilience. Power input: 4.5–5.5 V DC. RS485 interface: standard 5V logic with differential A+/B− signalling. Frequency coverage: 433–458.5 MHz, supporting 255 independent channels. Transmit power: precisely adjustable from −40 dBm to +20 dBm (100 mW) in 10 discrete steps. Receiver sensitivity: −114 dBm. Transparent serial rates: 1200–19200 bps (factory default: 9600). Air data rate: 10–100 kbps. Temperature tolerance: −25 °C to +75 °C. Measured open-field range: 500 metres. Leverages embedded MCU for intelligent serial framing and ID-based routing. Supports 31-byte payload per transmission. Enables flexible network topologies — configure as simple pair or expand to multi-node master-slave clusters using unique device identifiers. Configuration is limited to a protected 3-minute window after power application, triggered solely by 'AT+ENABLE=1'; no further AT access permitted — ensuring deterministic runtime behaviour. Validated for use across UK smart infrastructure: integrates natively with Wiser Home ecosystem, IP PTZ cameras (ONVIF/RTSP), Modbus temperature loggers, RGBW LED controllers, DIN-mount RS485 relays (R4D3C32, N4D8B08, N4D8C12), wireless gas/water meters, building access systems and remote telemetry gateways — enabling rapid deployment in residential, commercial and light industrial settings.
