The LSD4RF-2R717N30 is a wireless module manufactured by Lierda, compliant with the Restriction of Hazardous Substances (RoHS) standard. This module is designed for low-power, short-range communication such as that used in ZigBee, Bluetooth, and 2.4GHz ISM band applications. The module is comprised of a single-chip transceiver; an integrated interface circuit; and an antenna. The transceiver burns very low power during idle and transmission and includes an integrated synthesizer that supports all common frequencies in the range of 420 and 960 MHz. The interface circuit is based on a low-power CMOS design and supports the following typical signals: analogue data, digital data, UART, SPI, and I2C. The module's small size allows for easy integration into a variety of embedded systems.
