Hello, I recently got my hands on a Nucleo-U031R8 with a cortex-M0+ processor. My goal is to to reach 52 nA (using usb cable) in shutdown mode, but as of now the lowest i could go is 490 nA.
HAL_SuspendTick();
HAL_PWR_EnterSHUTDOWNMode();
The code above is all I used to enter shutdown mode, is there anything else I should do to reach the lowest possible current usage?
Thanks in advance.
