I-NUCLEO-LRWAN1 STM32 LoRa Arduino Extension Board

原廠連結：http://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-3rd-party-evaluation-tools/i-nucleo-lrwan1.html

USI^® in partnership with STMicroelectronics developed the LoRa^® expansion board for STM32 Nucleo (I-NUCLEO-LRWAN1). This board is an integrated solution allowing anyone to learn and develop solutions using LoRa^® and/or FSK/OOK technologies.

The I-NUCLEO-LRWAN1 features the USI^® LoRaWAN™ technology module, addressing low-cost and low-power wide area network (LPWAN) which comes with embedded AT-commands stack pre-loaded.

The I-NUCLEO-LRWAN1 can be controlled from an external host such as NUCLEO-L053 boards, running the embedded software I-CUBE-LRWAN. This software provides the means to set up a complete LoRaWAN™ node.

The I-NUCLEO-LRWAN1 is LoRaWAN™ class A certified and sustains the class C.

The I-NUCLEO-LRWAN1 includes the USI^® LoRaWAN™ module, Arduino™ connectors, a SMA connector, a 50 Ω antenna and three ST environmental sensors.

For more details about all the components of the LoRa^®-Middleware library, refer to the STM32 LoRa^® software expansion for STM32Cube user manual (UM2073).

The I-NUCLEO-LRWAN1 is supplied by a third party not affiliated to ST. For complete and latest information, refer to the third party website http://www.usish.com/english/.
