WM-SG-SM-42 LoRa Module

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 multi-

functionality 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.
