Wireless RF Transceiver 431-478MHz GFSK Data Transfer x 2
 

Product Number
RMB-CM12111
Product Name
Wireless RF Transceiver 431-478MHz GFSK Data Transfer x 2
Size (only PCB) 39.60mm(L) X 19.30mm(W) X 4.32mm(H) ±0.2mm
Net Weight 28g/1.0oz

Brief Introduction:

This package consists of two mini half-duplex wireless data transceiver modules and each such module is highly integrated with an ultra speed MCU and a powerful RF chip. With the introduction of the innovative yet higly-efficient encoding method, its anti-interference ability and sensitivity are significantly improved. Features like various channel options, ultra long transmission distance (1000 meters) or abundant interfaces (UART/TTL, RS-485 & RS-232) helps make the transmission of data of any size possible and eliminate the needs of writing transmission program and running complicated settings. A software application ("RF-Magic") is offered for free so that users can modify the settings of the module. Besides, its slim size and wide power supply range makes itself the most popular selection of many applications in different fields.

Features:

  • Ultra long transmission distance: 800-1000 meters @1200bps
  • Working frequency: 431-478Mhz (1KHz step)
  • +3.3-5.5V wide power supply range
  • -112dBm(9600bps) high sensitivity
  • Over 100 channels
  • GFSK modulation
  • Highly efficient cyclic interleaving error correction encoding
  • Flexible software programme option settings
  • Selectable RFID index
  • UART/TTL, RS-485 & RS-232
  • Large data buffer: 512bytes
  • Suitable for massive data transfer
  • Built-in watchdog ensures long-term operation
