My understanding is that the ADC reference voltage is 1.1V and that different input ranges can be achieved via software settable "attenuation" settings.
My question is about the accuracy and tolerance of the reference itself. 5%? 1%? drift over temperature?

Thanks!

In the "Espressif Products Ordering Information" document, under "Modules" is listed:
ESP32-WROVER-I / Sample / IPEX antenna...

Is there any other documentation for this module (schematics, package geometry, etc...)
What is the timeline for this module to be in production?
