Restrictions on GPIO pins
Restrictions on GPIO pins
Are there any special restrictions or notes on certain GPIO pins besides the strapping pins? I'm currently using ESP32-S3_DevKitC-1 and I want to connect a microphone (mono or stereo), speaker and a camera to it
Re: Restrictions on GPIO pins
Have you looked at Espressif's ESP32-S3-DevKitC-1 Documentation? It says, for example,
If you're not using a lot of GPIOs, looks like you have quite a few to choose from if all you need is a microphone and camera.For boards with ESP32-S3-WROOM-2 modules, the pins GPIO35, GPIO36 and GPIO37 are used for the internal communication between ESP32-S3 and SPI flash/PSRAM memory, thus not available for external use.
