Caveats: GPIO35 (battery monitoring) + don't use internal SD-slot as it's to capable of SD_MMC because of its pin-layout!

//################## GPIO-configuration ##############################
// Please note: GPIOs 34, 35, 36, 39 are input-only and don't have internal pullup-resistors.
// So if connecting a button to these, make sure to add a 10k-pullup-resistor for each button.
// Further infos: https://randomnerdtutorials.com/esp32-pinout-reference-gpios/
