Re: Any RTC chip known to work with ESP32 cam ?

Thank you for your reply !

Actually I wanted to see a (close-up) picture of the board after your modifications.

You said that "but after removing some components I got 3uA".

Re: Any RTC chip known to work with ESP32 cam ?

This would be my last resort as waking up ESP32-CAM would consume more energy and I intend to power the chip with a 3V battery. I hope to make it run on battery for at least 6 months (if I get 1 year out of that 3V battery, I would call it my success :) ) The main reason I shied away from using the ...

Any RTC chip known to work with ESP32 cam ?

Hi, I'm working on a project in which I want to put an ESP32-CAM in Deep Sleep and wake it only once per month, at the end of the month. Since ESP32 doesn't have a very good internal timer (i.e. I cannot tell it to wake up exactly on the last day of the month) I would like to use a RTC. Unfortunatel...

Re: ESP32-cam with ds1302?

Extra fact: I use the GPIO_13 pin (wake up) to receive a frequency sent to me by the CDM324 sensor, then analyze it, and after that, take a photo and save it in the SD, which also uses GPIO_13. All this works. But when using the DS1302, it does not work, and the 5 pins are connected, including VCC ...

wake up esp32 at the end of the month

Hi,

The subject says it all. Is it possible to wake up ESP32 from deep sleep at the end of each month ? I would like to use it only a few minutes on the last day of the month. Power consumption is very important, this is why I would like to wake it up as seldom as possible.

Thank you !
