Nucleo-G031K8 Extra 5 pins ?

Bcarpneter5 · ‎2024-01-21

Does anyone know the exact pin-out of these five pins? I cant find anything in the documentation. Hoping it will allow me to use an external programmer.

Hello @Bcarpneter5 and welcome to the ST Community :smiling_face_with_smiling_eyes:.

According to the schematic MB1455 this is a 5 pads for ST-LINK SWD interface and it is Not fitted.

Best Regards.

It is the SWD access to the interface STM32F103, Find it as CN2 in the Nucleo32 schematics.
