Any RTC chip known to work with ESP32 cam ?

Sorry for the late reply, I had notifications OFF for some reason...

Not sure you asked for photos of the assembly or photos taken by it, so here's both.

I changed the code, now I'm using Async Telegram Library which allows me to send photos in UXGA without problems.

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".

Only the DS3231 chip is needed, plus two 10k pull-up resistors for SDA and SCL, and the CR2032 cell. When an alarm is set and SQW is HIGH, the P-Channel Mosfet is open and the device is off, the quiescent current is very low which allows for 5 days of a photo being sent to Telegram every 2min.

There is still much room for improvement.
