WM-SG-SM-42, I-NUCLEO-LRWAN1, USI, LoRA, 에드웍스

LoRA 모듈은 광범위한 통신 영역을 확보해야 하는 IoT 분야에 주로 적용하고 있는 LPWA 모듈로서, NBIOT나 CAT.M1 방식의 LPWA와 다른 점으로 손쉽게 단독망을 구축할 수 있다는 것을 특징으로 하고 있다.

Dimension: 12 x 13 x 2.0mm

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 UFL connector.

The WM-SG-SM-42 provides for the highest-level integration for electronic accessories, featuring integrated Lora.

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.
