https://devzone.nordicsemi.com/f/nordic-q-a/104912/shutting-down-npm1100I have a device that needs to be shutdown once the voltage drops to 3.0v to protect the battery. I see the (optional) Battery Monitoring Circuit, which is fine. I understand how that works. https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_npm1100en-USTelligent Community 13Wed, 25 Oct 2023 12:13:17 GMThttps://devzone.nordicsemi.com/thread/452257?ContentTypeID=1Wed, 25 Oct 2023 12:13:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d82d68af-5aa0-43d9-9e3d-b21d2a12090dmathiaso<p>Hi again, Michael!</p> <p>As Robin is suggesting, you can exit Ship mode by connecting the USB.
