I'm currently working on my project that uses the following:

  • Arduino Nano
  • accelerometer
  • sim800l
  • neo GPS
  • hc-05
  • buzzer

And all of these are working with the power coming from my laptop and its working like i wanted it to be. Now heres the problem, i wanted it to be powered by a battery and i bought a 3.7v li po battery hooked it up with TP4056(Charger) and then to MT3608(power booster). The Nano,accelerometer,buzzer works fine but the gps and sim800l is not lightning up and i think it does not get enought power. Any suggestion how can i make this work. I want it to be compact as possible because im gonna fit it in a small case.

It would be much more power efficient (close to a factor of 2) to use a 3.3V Arduino, and a linear regulator to convert the 3.7V LiPo output to 3.3V. The Sim800L can run directly from the battery.
