 Eason wireless module

Wireless module yl-800iu

Chip solution Loratm spread spectrum modulation technology
carrier frequency : 420 ~ 450MHz (customizable)
Transmitting power :+20dBm
Communication distance : up to 3-5km
Product size : see the specification for details
communication interface :TTL/RS232/RS485
Product introduction Yl-800iu is a high-performance, low-power, long-distance micro power RF wireless data transceiver module, internal automatic spread spectrum calculation and preamble CRC error correction processing, does not change any user's data and protocol, uses half duplex transparent transmission mechanism to realize wireless replacement function. The RF chip of the module is based on the spread spectrum frequency hopping technology, which surpasses the existing GFSK module in stability, anti-interference ability and receiving sensitivity. With STM low-power and high-speed processor, the data processing ability and operation speed are improved. users can flexibly configure the operating frequency, serial port rate, spread spectrum factor, working mode, spread spectrum bandwidth and other parameters of the module according to the actual needs through the host computer software configured by our company, which is easy to operate and easy to use.
