ESP32 CAM alimentation via 3.7V LIPO battery

Other Hardware General Electronics
1

Hi,

I want to aliment an ESP32 CAM using a 3.7V LIPO battery AND to can charge the LIPO battery without have to change anything on the wiring
(only to plug an USB cable into the charger for to charge the battery and aliment the ESP32 CAM if the LIPO battery is empty)

I think to use something like this for to dynamically recharge the LIPO battery using an USB câble

And perhaps this if a 3.7V to 5V conversion is necessary for to aliment the ESP32 CAM

=> is it possible ?

3

Or is this type of component is more better for to do this ?

4

Or have I to use the circuitry as proposed here ?
(I prefer limit the number of components/wiring because want to store the entire system into a very limited volum)

5

PS : It's for to work with an LED emitter + a LED recepter on the ESP32 CAM side : is a 5V solution a better solution than a 3.3V solution for to handle this ?

Hi @Yannoo .

I use in my projects with ESP32_CAM this module.

I remove the USB Type A connector, and solder the wires to the ESP directly onto the Charger/Stepup board.
