Pin Location for Arduino ESP32 Nano DAC

[studiopeters]

I am trying to connect a circuit to the Arduino ESP32 Nano DAC pin. What is it label on the physical board? I get its GPIO25, but what pin is that on the Arduino Nano ESP32?

Hi @studiopeters.

@studiopeters

the Arduino ESP32 Nano DAC pin

The ESP32-S3 microcontroller of the Arduino Nano ESP32 board doesn't have a DAC. You are probably seeing information about the classic ESP32 microcontroller, which does have a DAC.

For future reference, if you need to determine the GPIO to Arduino pin number mapping, check the pinout diagram. You can see the pinout diagram by going to the Nano ESP32 documentation page:

https://docs.arduino.cc/hardware/nano-esp32/

Then click the icon under the board graphic that looks like a pin header. The pinout diagram will open.
