I would like to get ESP32 cam to work on weekly basis. I have two ways to do this
- ask NTP server. Disadventage
– if internet connection somehow fail, ESP32 CAM will not work properly as well.
– Wfi is battery consuming operation
2. RTC module :DS1307, DS3231
which pin do I use for esp32 cam i2c?
I haven’t experimented with the ESP32-CAM and an RTC module.
Are you using the microSD card? You may find useful taking a look at the ESP32-CAM pinout: https://randomnerdtutorials.com/esp32-cam-ai-thinker-pinout/
