433MHz RF Data Module 100mW Wireless Data Transfer 1km RS232 RS485 TTL
100mW RF Data Module 433MHz Wireless Data Transfer 1km RS232 RS485 TTL
Introduction
LS-U100 is a UHF band 100mW data module. It transmits around 1KM LOS. This module adopts transparent transmission. Users don’t need any program knowledge. Designed with good performance IC TI CC1020 and high speed MCU, LS-U100 is an excellent RF transceiver. It has the advantage of small size, low power consumption, long transmission distance, and also, strong anti-interference ability.
