This board is an overly complex design. The DS2483 onewire host chip
will work on a 3.3V I²C bus and gives you a 5V onewire at the same time.
External circuit: two resistors.
If you only want to connect a single DS18B20, the cheap&dirty solution
of connecting it (and a 1k pullup to 3.3V) to GPIO4 is sufficient.
Kind regards
