* If you want to monitor the battery-voltage, make sure to enable `MEASURE_BATTERY_VOLTAGE`. Use a voltage-divider as voltage of a LiPo is way too high for ESP32 (only 3.3V supported!). For my tests I connected VBat with a serial connection of 130k + 390k resistors (VBat--130k--X--390k--GND). X is the measure-point where to connect the GPIO to. Please note: via GUI upper and lower voltage for visualisation of battery-voltage (Neopixel) is available. Additional GUI-configurable values are interval (in minutes) for checking battery voltage and the cut off-voltage below whose a warning is shown via Neopixel.

As per default you have to invert this signal and connect it to GPIO22.

* Enabling `SHUTDOWN_IF_SD_BOOT_FAILS` is really recommended if you run your Tonuino in battery-mode without having a restart-button exposed to the outside of the Tonuino's enclosure. Because otherwise there's no way to restart your Tonuino and the error-state will remain until battery is empty (or you open the enclosure, hehe).

* Enabling `PLAY_LAST_RFID_AFTER_REBOOT` will tell Tonuino to remember the last RFID-tag played after reboot. So rebooting Tonuino will end up in autoplay.
