<![CDATA[RTC vs ESP32 timer]]>Hello!

I'm looking at the "rtc" example of M5 Dial. It shows how to get time from either RTC or ESP32 timer.

What is the practical difference in use of these?

Is there a benefit of using one versus the other?

Thank you!

It is literally hardwired to the battery which means you can keep track of the clock even while the M5Dial board is shut down - that is as long as you always keep an un-depleted battery connected to the board. The BM8563 chip consumes less than 3 µA@"stdLiIonVoltage"
