I need to power a nodeMCU (as far as I know it can work with 3v3 but I use some I2C modules that need 5V so .. let's power everything with 5V)
I have a Li-ion battery (3.7V) I have a TP5046 based module (here) to manage the loading / discharging of the battery
This will lead to a rechargeable 3.7V power supply.
Then I have a one of those cheap power boosters from china (here) that brings the voltage up to 5V .. soooo
Im a hobbyist electronic and I like to think about my modules as lego pieces that I plug here and there but .. Any recomendations on how to pierce the things together ??
This is my proposal:
