Product details

RS485 433MHz Wireless Modem Kit

Unit size: 74 × 24 × 16 mm (no antenna); input voltage: 4.5–5.5 V DC; interface: RS485 (5V, GND, A+, B−); frequency coverage: 433–458.5 MHz with 255 channel options. Transmit output: adjustable from −40 dBm to +20 dBm (100 mW max) in 10 steps. Receiver sensitivity: −114 dBm. Transparent serial transmission supports baud rates 1200–19200 bps (9600 bps default); extended to 10–100 kbps via AT command. Maximum payload per transmission: 31 bytes. On-chip MCU manages serial interface, ID-based addressing, and channel selection. Supports both point-to-point (2-unit) and scalable multi-node (≥3-unit) operation — one master broadcasts to many slaves, or any slave may initiate transmission under controlled arbitration, mirroring wired RS485 bus discipline. Operational temperature range: −25°C to +75°C. Verified open-area range: up to 500 m at 10 kbps. Compatible with IP PTZ cameras, Modbus temperature/humidity sensors, LED controllers, RS485 relay modules (R4D3C32, N4D8B08, N4D8C12), smart electricity/water meters, Wiser Home ecosystems, electronic door locks, and remote SCADA telemetry systems.
