Clarification re. GPIO matrix and IO Mux

Hi, The document ESP32 Chip Pin List states the following: The page "GPIO_Matrix" is for the GPIO-Matrix. The signals of the on-chip functional modules can be mapped onto any GPIO pins. Some signals can be mapped onto a pin by both IO-MUX and GPIO-Matrix, as shown in the column tagged as "The same i...

Re: Voltage/current ratings on ESP32 pins

Well, perhaps it does. Section 5 of https://espressif.com/sites/default/files/documentation/esp32_datasheet_en.pdf specifies the electrical characteristics, and 5.1, table 7 might be what I want. However, the absolut maximum rating for input high is given as 3.3V. Does that mean that the ESP32 doesn...

Voltage/current ratings on ESP32 pins

I believe I've read through every document I can find, but nowhere have I seen information regarding voltage and current limits for the ESP32 pins in their different configurations (ADC, I/O etc). Is this information actually missing or have I just overlooked them? If they indeed are there, would so...
