Product Description                                                                                                 

  • WT-800T is a high performance, low power, long-range wireless data micro-power RF transceiver module, internal automatic spreading calculation and preamble CRC error correction processing, without changing the user’s any data and protocols, using a half-duplex transparent transport mechanism to achieve wireless communicate function.
  • The RF chip of Module is based on spread spectrum frequency hopping technology, the stability, anti-interference ability and receive sensitivity are beyond existing GFSK module. configured of Low-power high-speed ST processor, data processing capacity, the operation speed are improved.
  • Users can configure our PC software, or by microcontroller commands, according to the actual demand, flexible configuration module working frequency, baud rate / parity, spreading factor, spread spectrum bandwidth and other parameters, simple operation, easy to use .

 

Features

  • Based on LoRaTM spread spectrum modulation techniques.
  • Half-duplex communications, serial data transparent transmission.
  • 420~450MHz, Free application band, the other band can be customized.
  • Produce without debugging, 3.4-5.5V voltage range, can be customized 3.0-3.6V.
  • Micro-power transmission, standard + 20dBm output, seven adjustable levels.
  • Receiving sensitivity up to -148dBm, the maximum transmit power + 20dBm.
  • High-efficiency forward error correction coding techniques and frequency hopping mechanism, enhance the anti-interference ability and reduce the error rate.
