Hi I’ve got a question regarding Wio-E5 mini. I was planning to use it together with battery but my initial plan for the setup was as follows:

             <-----> 3.7V LiPo battery
TP4056
            <------> Pololu 2122 S7V8F3 (buck boost, step-up/down) <-----> Wio-E5

I want to add this voltage regular in order to keep the voltage stable when the battery discharges. The thing that worries me is that I have found on the Wio-E5 wiki that power supply is expected to be used with 3.7V-5V whereas my Voltage Regulator supplies 3.3V. Will this be enough to power up board?

Thanks I tested it and it seems to be working fine.
