XIAO ESP32S3 sense - Free pin for latch Button while using the camera board extension

I would like to use a physical button to start the recording. Which pins are free and can be used while using the camera board extension?

Hi Francesco,
If your using the Standard interfaces then the first four PINs are pretty standard

1x UART, 1x IIC, 1x IIS, 1x SPI, 11x GPIOs (PWM),
 9x ADC, 1x User LED, 1x Charge LED, 1x B2B Connector
 **(with 2 additional GPIOs)**
1x Reset button, 1x Boot button

You can use the GPIO 12 & 13 on the camera pcb if you don’t need the Microphone.
