ESP32-S3 GPIO Functions List

Postby August » Sun Nov 06, 2022 10:16 am

I'm new in ESP32 and want to use the LED_PWM unit in the ESP32-S3 using ESP-IDF. I've read the document about it on this link. But I don't know which GPIOs can be connected to those PWM outputs. I just need a document with a table of ESP32-S3 peripherals and their associated GPIOs. For example, which GPIOs are connected to PWM outputs. Thanks

The ESP32 series chips all have a GPIO matrix, which means that (with the exception of some very specific peripherals) you can route any peripheral signal to any GPIO. In practice, this means you can use any GPIO (that is not otherwise occupied) as a LED_PWM output.
