ESP32 Forum

Hi!
I decided to dive into the world of microcontrollers by making my own little watch. I successfully prototyped it on an arduino board, but I'd like to shrink its size so I searched for the smallest esp32 with an RTC built right in. I found the TinyPICO to be perfectly sized for my project but I realised it doesn't contain an RTC
Does anyone have an idea of a very small ESP32 board with RTC ? I have to admit I'm a bit lost.

Thank you!

update : I think I may be retarded. I believe the rtc is in the chip itself so it doesn't matter what dev board you plan on using.

Note that the RTC in the ESP32 chips do not support battery backup. If you need to keep time while the power is off (and getting it again on power-on using e.g. NTP is not an option), you may want to add an external RTC.
