 Eason wireless module

Wireless module yl-800il

Chip solution Loratm spread spectrum modulation technology
carrier frequency 450 MHz ~ 450 MHz
Transmitting power : maximum transmit power + 20dbm
Communication distance : up to 3-5km
Product size :41.9*23.6*4
communication interface :TTL/RS232/RS485
Product introduction Yl-800il 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, effective data ratio and spread spectrum bandwidth of the module through the host computer software configured by our company, which is easy to operate and easy to use.
