/* GPIO pins definitions
*
* pin layout is compatible with ESP32-CAM module for prototyping
* LEDs aren't avaible on ESP32-CAM but DEBUG LED (Camera connector)
*
* on ESP32-CAM the following pins are already used:
* - CSI_MCLK (GPIO0)
* - U0TXD (GPIO1)
* - U0TXD (GPIO3)
* - FLASH (GPIO4)
*
* on ESP32-PICO-D4, the following pins are used for connecting the
* embedded flash:
* - CLK (GPIO6)
* - SD0 (GPIO7)
* - SD1 (GPIO8)
* - CMD (GPIO11)
* - GPIO16
* - GPIO17
