Introduction

The WM-SG-SM-42 LoRa module which refers as "module" is a small size module and consists of a SEMTECH SX1272, an authorization chip and a U.FL connect. The WM-SG-SM-42 provides for the highest-level integration for electronic accessories, featuring integrated Lora.

The small size & low profile physical design makes it easier for system design to enable high performance LoRa connectivity without space constrain. This multifunctionality and board-to-board physical interface provides UART interface options.

For the software and driver development, USI provides extensive technical document and reference software code for the system integration under the agreement of SEMTECH and ST.

Hardware evaluation kit and development utilities will be released base on listed OS and processors to OEM customers.
