 Eason wireless module

Serial wireless data transmission module yl-5000

Chip solution :Si4432
carrier frequency :433MHz
Transmitting power : maximum 37dbm
Communication distance : open land 5-10km
Product size :120mm*85mm*38mm
communication interface :TTL/RS232/RS485
Product introduction : Si4432 RF wireless scheme based on silicon labs, adopting GFSK modulation technology, with ST single chip microcomputer, half duplex wireless data transmission station. It contains wireless transceiver communication program, which does not change user data and protocol. Users can realize data transparent transmission without programming and controlling data receiving and sending process. It is compatible with TTL, 232485 and USB serial ports. It is convenient to connect with various serial port devices of users, and can directly replace the application of wired transmission.

Product overview
        YL-5000 It is a wireless transparent data transceiver module with high stability, low power consumption and high cost performance. Do not change any of the customer's data and protocol, complete the wireless data transmission function Compared with other modules, the module has the characteristics of high sensitivity, long transmission distance, high communication rate, automatic communication protocol conversion and data transmission control. Users can flexibly configure the serial rate, working channel, transmission power, communication rate and other parameters of the module according to their own needs through the host computer software configured by our company.
