20dBm RS485 Wireless Modem 433MHz

Compact module measuring 74 × 24 × 16 mm (antenna excluded), designed for 4.5–5.5 V DC operation with native RS485 interface (5V logic, GND, A+, B−). Operates across 433–458.5 MHz band with 255 programmable channels; output power tunable from −40 dBm to +20 dBm in 10 discrete steps; receiver sensitivity reaches −114 dBm. Serial transparent transmission supports standard baud rates (1200–19200 bps, default 9600) and variable over-the-air data rates (10–100 kbps). Each transmission frame carries up to 31 bytes. Functions as drop-in wireless extension of RS485 bus: supports point-to-point or multi-drop topologies using ID-based addressing — one master can broadcast to many slaves, and any slave may transmit (with single-transmitter arbitration). Valid for use in IP PTZ camera control, Modbus temperature monitoring, LED signage systems and other serial-based IoT applications.
