描述

串行收發器模塊是一款低成本,高性能透明 FSK 收發器,工作頻率為 434 MHz。它具有體積小,輸出功率高,靈敏度高,傳輸距離遠,通信數據速率高等優點,可自動設置通信變化,數據接收和傳輸控制。具有 UART 接口,僅提供 UART 數據就很容易實現無線數據傳輸。用戶可靈活設置 UART 波特率,頻率,輸出功率,數據速率,頻率偏差,接收帶寬等參數。這是您設計無線數據傳輸產品的理想選擇,可廣泛應用於無線數據傳輸領域。

單個模塊無法工作,請獲取兩個或更多這些模塊。請注意,此模塊不適用於 433Mhz 無線串行發射器模塊 - 1 公里。

Description

Serial transceiver module is a low cost, high performance transparent FSK transceiver with operating at 434 MHz. It features small size, high output power, high sensitivity, long transmission distance and high communication data rate with auto set up for communication change and data receiving and transmission control. There is UART interface, it is easy to realize the wireless data transmission with only providing the UART data. It is flexible for the users to set the UART baud rate, frequency, output power, data rate, frequency deviation, receiving bandwidth etc parameters. It is your ideal choice for designing wireless data transmission products which can be widely used on wireless data transmission field.

The single module can not work, please get two or more of these modules. And please note that this module do not work with the 433Mhz Wireless Serial Transmitter Module - 1 Kilometer.

 

Features

  • Wireless communication frequency band is 434M 

  • Multiple types of serial port transparent transmission modes have respective features, and the mode is changed by command

  • User needn't program the modules, and four modes are only responsible for receiving and sending serial port data, and are convenient to use

  • Low current consumption; the idle current is 80μA, 3.5mA or 22mA, depending on the selected mode

  • The number of bytes sent to serial port of module unlimited to one time

  • All functions and parameters are changed by command, and can be saved in case of power failure

 

Specification

  • Working frequency: 434Mhz

  • Supply voltage: 3.3V to 5VDC

  • Communication distance: 1m to 40m indoor

  • Serial baud rate: 1.2Kbps to 115.2Kbps (default 9.6Kbps)

  • Receiving sensitivity: -112dBm to -95dBm

  • Transmit power: -30dBm to 10dBm

  • Interface protocol: UART/TTL

  • Operating temperature: -40℃ to +85℃

  • Dimensions: 27.8 x 14.4 x 4mm
