Schematic Request for I-NUCLEO-LRWAN1

Gencay · ‎2026-01-18

Hello, I have a pair of these boards on my hand, there is no information regarding WM-SG-SM-42_Shield_v1.0 board its jumpers pinout etc. Could you please provide a schematic or more detailed guide whats available? I've seen on early posts some got the reference design via mail. Could you please provide for me also?

Thanks!

The board uses a module from USI - they have a GitHub repository, which includes the schematics:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Unfortunately, the I-NUCLEO-LRWAN1 has been discontinued for a long time, which is why there is no documentation for it from ST anymore. If nothing can be found in the depths of the (supposedly) never-forgetting internet, unfortunately no one will be able to help you.

Sorry I can't give a more pleasant answer.
