RTC and RAM support

Postby KernelPanic » Tue Oct 24, 2017 6:43 pm

Dear Sirs and Madams!

Does ESP-WOORM-02 pcb include some kind of RTC (Real Time Clock) and/or RAM, connected to battery or supercap in case of knowing time and storing settings at powerfailure event?

The ESP8266 does include low power RAM, which works in deep sleep mode as well.
But there is no RTC to keep track of time-of-day. Also, there is no separate power rail for battery backed RAM (it is just intended to keep data during deep sleep mode).
