How can I reduce the power consumption as much as possible and disable the j-link on the Nucleo-L073RZ?


Je suis en train de développer une carte avec un stockage par supercap, je l'ai conçu pour une consommation de 40uA comme selon ce qui est écrit dans le datasheet, cependant j'arrive qu'à 3mA et j'utilise le mode "standby" écrit et trouvé sur internet. Pouvez-vous m'expliquer comment on peut désactiver la consommation du J-Link, de manière physique ou par le soft.

Nucleo have st-link, not j-link. Perhaps you measure in wrong place. Do you use idd pins to measure?​


You might do better just physically removing the ST-LINK section of the board, and wiring connectivity when/if you need it for programming.

Closing the thread as it is the duplicate of the same post in English. Please further discuss here:

How to reduce the consumption of the Nucleo-L073RZ board to less than 700uA? How to disable J-Link part on the board?
