Re: Current Limits

Actually, no. There was some fuzz about the output current handling capacity for a while, but as far as I know, the 40mA number is correct: the 12mA number we used initially was a holdover from the ESP8266, but for the ESP32 we improved the IO-pads, so they can handle a larger current now. :lol: es...

Re: esp32 with ULP and RTC using AA batteries for a year

With the default configuration (20ms ULP wakeup period), average current consumption in deep sleep mode is 16uA.

If it wakes up only once per day for 10 sec it should use <500mah per year

At 1.5v, so half of that at 3v.

Re: Current Limits

No it is 12mA. 40mA is for logic signals with capacitive loads.

Re: ESP32 wake up time and low power consumption

It depends what you want to do when you wake up. Look at wake stubs and ulp coprocessor programs.

Re: esp_image checksum failed while reboot test

If it seems to get stuck randomly but works on the next try you could modify the 2nd stage bootloader to restart instead of quit.

Re: What is the ESP32-WROVER-B?

It is probably the second gen version of wrover like the wroom-32d/u so it should have improved rf and more certifications.
