Wireless Transceiver Serial UART (1000m Range)

Description

This serial UART wireless module, is 1km distance range in open area (line of sight) and 433 MHz frequency. This module powerful wireless chip which is RF chip (check datasheet) with its 100mW (20dBm) power. Also (like ZigBee) you can adjust the wireless module parameters (baud rate, channel, and power dBm) by connecting the module to pc USB port using our ZigBee-USB adapter and you can write the AT command using hyper-terminal. It can work as one to many. We have worked out this wireless module with Arduino and made a simple code. Features One to many, works like walkie-talkie. Serial UART, Can work directly with your Micro-controller or Arduino TX/RX Long-distance wireless transmission (1000 m line of sight with baud rate 5000 bps). Easy to use (as easy as Zigbee) Maximum 100mW (20dBm) transmitting power . Default 9600 baud. Can operate at higher speed but with the expense of more error and shorter range. Baud rate/channel can be modified using specific AT command. You can change the wireless module parameters (baud rate, channel, and power dBm) by AT command. Specifications Supply voltage: 3.2V to 5.5VDC Communication distance: 1,000m (line of sight) Working frequency: 433.4MHz to 473.0MHz. Serial baud rate: 1.2Kbps to 115.2Kbps（default 9.6Kbps） Receiving sensitivity: -117dBm to -100dBm Transmit power: -1dBm to 20dBm Interface protocol: UART/TTL Operating temperature: -40℃ to +85℃ Dimensions: 27.8mm x 14.4mm x 4mm Pin Definition Power, 3.3 V to 5 V.
