Introduction 
LSD4RF-25410N15 Wireless Module is designed based on TI Transceiver 
CC2500and CC2590. It is a high performance 10mWSMD IOT wireless 
Transceiver that can be used in a wide range of short distance IOT 
communication. It has low power consumption, high resistance to 
disturbance ,small in size and low cost. The module adopts SMD wireless PCB 
antenna, providing a compact size.
