ESP32 C3 Mini1 module

[tleracorp]

I am able to program the ESP32C3Mini1 module with native USB (no CP2102 or FTDI UBS-to-UART tranceiver) which is really cool.

I notice that pins GPIO0 and GPIO1 have an alternate function for a 32kHz crystal; does that mean the ESP32C3Mini1 has an RTC but this is just not active in the Arduino core?

Similarly, I tried the wake-on-pin (sensor interrupt) example for the ESP32 on the ESP32C3Mini1 which did not compile. I was told on the ESP32 Arduino github site that this cannot work for the ESP32C3Mini1 since there is no RTC processor, or maybe not one running in deep sleep.

"esp32-c3 has no processor running during deep sleep, "

So my question is, is it simply impossible to wake from deep sleep via external interrupt using the ESP32C3Mini1 module or is this simply a matter of activating the embedded RTC?

Thanks for any help!
