Introduction
LS-U1000 is a UHF band 1000mW data module. It transmits around 2-3km 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-U1000 is an excellent RF transceiver. It has the advantage of small size, low power consumption, long transmission distance, and also, strong anti-interference ability.
