Hello, I am powering an Arduino Pro Mini 5v with a Lipo battery which has a maximum voltage of 4.2v and a minimum of 3.3v. I also need to power an NRF2401n+ with .9v - 3.6v but the voltage from a fully charged lipo is too high. I know I could lower the voltage with a diode, led or a resistor network…

Powering a 5v Arduino with 3.3v and using a resistor network for voltage droping
