Hi, the lowest low power consumption can be achieved depends on the program sleep logic and the logic of the code, so we can work on these two directions,The wiki in this forum uses nrf52840, but it may give you an idea:
I’m affraid the thread you point is very NRF-specific and won’t apply easily on ESP32S3 HW.
Anyway, I’ll have a look at the part thats stop the flash chip. Is it the same with the PSRAM chip? Do we need to shut it down as well?
My goal is to do the simplest code possible to achieve the lowest consumption, having a simple GPIO or timer wakeup trigger. It’s not really about code logic from my perspective, only adding the missing parts from this trivial skeleton (timed wakeup):
delay(1000); //Take some time to open up the Serial Monitor
Serial.println("Going to sleep now");
/* Please help me insert here smart code to shutdown everything to achieve the lowest deepsleep consumption */
esp_deep_sleep(2 * 1000000);
//This is not going to be called
Utilize the lowest power sleep or standby modes available on your microcontroller or system-on-chip (SoC). These modes study in usa scholarship click to apply can significantly reduce power consumption by disabling or minimizing active components.
