I-NUCLEO-LRWAN1 Still Supported?

Hi all,

As part of a uni project we are developing a LoRaWAN Weather station project.

We have free access (the team is operated on a limited budget) to a I-NUCLEO-LRWAN1 board. This appears to be a very good option as the board has all the integrated sensors required, and is compatible with Australian frequency.

How good is the support and integration with current development tools, I see the suggested board on the datasheet is still currently sold (NUCLEO-L053R8). 

Does anyone have experience with this board, or can point in the direction of something more suitable?

Thanks

Hello @sr71brd and welcome to the ST Community.

The I-NUCLEO-LRWAN1 is an obsolete product (as you can see on the product webpage). If you are looking for a product to establish a LoRaWAN connection based on the STM32, i suggest you use the STM32WL (This series provides a portfolio of System-On-Chip solutions integrating both a low-power microcontroller and a long-range, energy-efficient sub-GHz radio (that support the LoRa transmission for LoRaWAN) on the same chip.). As a evaluation board, you may use the NUCLEO-WL55JC without a need to a host board (all in the same SOC).

Best Regards.

As @STTwo-32 said, the I-Nucleo-LRWAN1 is obsolete:

It has been for a long time and, to be frank, the support was never great in the first place.

If you want a challenge, the schematics of the USI module can be found;  it just uses a standard STM32 and Semtech chips - so you could (in principle) write your own code...

 

Apart from the WL SoCs already mentioned, there is also the B-L072Z-LRWAN1 - which is still marked as Active:
