AtomS3 Deep Sleep Current?

  • Most of my projects require devices that can achieve low power deep sleep modes so that they can last a long time on batteries. I had stopped using M5Stack products in the past solely because they had poor low power current consumption. Now that they've started using esp32-s3's I'm hopeful that I can use their products for low power applications. I would love to see a deep sleep current consumption of less than 1ma.

    Anyone had a chance to measure the deep sleep current on an AtomS3 with everything powered off?

  • Hello @rdlaner

    on my M5AtomS3 (with display) I measure about 257 uA in deep sleep when powered via Groove port 5 V and running this code.


  • @felmue great! thank you so much for the data!
