Just purchased 2 I-NUCLEO-LRWAN1 - they look to be great. I would really like to know hardware details about the jumpers and connectors.

Specifically, I would like to access serial TX/RX for the USI module.

Thanks in advance!

Pretty sure the primary serial to the AT commands is through the D0/D1 pins of the shield connector.

PM me your email address for the schematic. The Murata part has the newer radio and larger L0 part.

Hi Clive,

D0/D1 works fine – thanks

Did you mean to attach a schematic to your email – none was received and I am still trying to figure out the JP1-4, JP12, etc.

With thanks and best regards,

Nic

Email should have contained a Google Drive link, can see it in the Sent Mail here, so perhaps Outlook ate it, PM'd the link to you here
