        Q: Can I get 5V on the Output with 3.7V Li-on battery connected to module? It should be possible, because of boosting function, is it true?
        A:
        In fact, it should not have the boost function, but the output is 5V, I have not tried to link the 3.3V voltage, maybe you can try.

        Q: What is the minimum input voltage? I tried to attach 3.7 volt battery but could only get 4.7 volts on the output. Thx
        A:
        Sorry, I have not tested the minimum voltage. The output of 4.7V may be normal due to load conditions.
