It's the same as rev0: 5uA with the default configuration (RTC_FAST_MEM powered on). I have posted measurement results some time ago: https://esp32.com/viewtopic.php?f=2&t=1 ... t=10#p5473

temp4eb: Thanks for the photo... Could you please make a current measurement with CHIP_EN input pulled low?
Hi ESP_igrr,thanx for the post link you provided!I got the 5uA result after modify the code.

Can this Modification be added to the Arduino core too?

Hi, still no news for arduino core ?

I measure 500uA in deep sleep with minimal hardware (two capacitors 100uF and 10uF between GND and VCC).

How to deal with this ?

I measure 500 uA with arduino deep sleep function. I am using minimal hardware configuration.

I even tried pcbreflux esp-idf example of deepsleep for 10 sec, still 500 uA.

For measurement i use INA219 with an Arduino UNO.

Any idea ?

Edit : It was an hardware issue, probably from the fact that the esp was previously powered with 5V :oops: .

With a new one the deep sleep consumption was 5uA
