Product details

433MHz RS485 Wireless Transceiver 20dBm

Dimensions: 74 × 24 × 16 mm (without antenna); weight not specified. Operating voltage: 4.5–5.5 V DC. Interface: RS485 (5 V, GND, A+, B−). Frequency range: 433–458.5 MHz, with up to 255 configurable channels. Transmit power adjustable from −40 dBm to +20 dBm (100 mW) across 10 levels. Receiver sensitivity: −114 dBm. Air data rate: 10–100 kbps (synchronised with UART baud rate: 1200–19200 bps, default 9600). Packet size: up to 31 bytes. Built-in MCU enables serial communication with external devices. Supports transparent point-to-point and point-to-multipoint transmission via device ID configuration. AT command mode available only within first 3 minutes after power-on (AT+ENABLE=1); thereafter, all AT strings are treated as payload. Operating temperature: −25 °C to +75 °C. Enclosure material: plastic housing with metal internal components. Package includes 2 transceivers with enclosures. Designed for reliable bidirectional wireless RS485 extension: two units operate as peer nodes; three or more require one master and multiple slaves — replicating wired RS485 bus behaviour (master broadcasts, any slave may transmit, all receive, single-transmit arbitration enforced). Ideal for industrial telemetry and distributed control where wiring is impractical. Used in IP PTZ camera control, Modbus temperature sensor networks, LED lighting systems, RS485 relay banks, remote telemetry, wireless metering, home automation hubs, access control panels, and smart utility metering — wherever robust, low-latency, long-range serial extension over 433 MHz VHF/UHF band is required.
