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 userâs 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 . Â Features Â Ã Based on LoRa TM spread spectrum modulation techniques. Â Ã Half-duplex communications, serial data transparent transmission. Â Ã 420~450MHz, Free application band, the other band can be customized. Â Ã Produce without debugging, 3.4-5.5V voltage range, can be customized 3.0-3.6V. Â Ã Micro-power transmission, standard + 20dBm output, seven adjustable levels. Â Ã Receiving sensitivity up to -148dBm, the maximum transmit power + 20dBm. Â Ã High-efficiency forward error correction coding techniques and frequency hopping mechanism, enhance the anti-interference ability and reduce the error rate. Â Ã Supports serial wake, ready to send and receive data, no periodic wake-up time. Â Ã Support air wake, AUX signal can be given via the module, Wake user device. Â Ã CAD detection LoRaTM signal, to prevent accidental wake. Â Ã Can work through the command switch module supports serial wake up, ready to send and rece
