如果您想在ESP32-C3上实现断电后RTC(Real-Time Clock)继续走时,可以考虑以下几种方法: 使用外部RTC芯片:您可以连接一个外部的RTC芯片,例如DS1307或DS3231等,这些芯片通常具有内置的锂电池,可以在断电时保持走时。将外部RTC芯片的VDD引脚连接到ESP32-C3的电池或电源,并将时钟信号线连接到ESP32-C3的GPIO引脚上。
To get things clear, the ESP32’s internal Real-Time Clock (RTC) can keep track of time even when the main processor is powered off or in deep sleep. You can use the ESP32 RTC to keep track of time without using much power or affecting the main processor.Butit still requires power ...
I cannot find anywhere that states the accuracy of the RTC Clock when the Internal 8.5 MHz oscillator, divided by 256 (~33 kHz) is selected. I know that using an external RTC or an external crystal is the most accurate, but perhaps the internal RTC is accurate enough for my purposes....

The main pins of RTC DS3231 modules are: VCC:Connect this pin to the positive terminal of your power source. GND:Ground connection. SDA:Serial Data pin (used for I2C communication). SCL:Serial Clock pin (also part of the I2C interface). ...
For those seeking integration/inclusion of ESP32, using an surface-mount module board with ESP32 inside is often more desirable, since such modules combine an ESP32 chip, 40 MHz crystal (clock), flash memory chip, and appropriate “glue” components into a ready-to-use, compact assembly. ...
