LS-S100 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-S100 is an excellent RF transceiver. It is small enough to be used in restricted spaces.
