Hi guys, looking for some advice.
I'm working on a project that uses an Arduino nano a 1000mah 1s lipo (3.7v) a charge controller and a voltage booster capable of outputting 2AMPS (I believe the SIM800L EVB v2 needs 2amps at peak).
See my attachment for the current wiring.
I am wanting to know the best way to wire power to the Arduino, directly from the dc booster because the Arduino needs 5v? or some other way? The worry about powering the arduino from the booster is that it will no longer be delivering the 2amps needed to the SIM800L EVB v2 module, because the arduino will be pulling some amps of its own. Is the easy solution to get another booster and wire that the the lipo then to the arduino?
Thanks
