Project Description:
*******

This is the most versatile 3.3V regulated Power supply; because it also has a lithium-Ion / Lipo Battery charger. And after looking at its features, you gonna be like wow!

And trust me sooner or later you gonna need this 3.3V power supply. Because with the help of this circuit using a 5V adaptor, or a cell phone charger, you can directly power up 3.3V compatible controller boards and sensors.

And if you want to provide battery backup to your 3.3V compatible controllers or sensors, there is no need to worry, because you can also use this circuit as a Lithium-Ion / Lipo battery charger.
You can charge this battery using a 5V power supply, or you can even use a small 6V solar panel. You can solder the Solar Panel wires over here, and the wires of the Lipo battery or Lithium-Ion battery over here. Using this switch I can turn ON/OFF the 3.3V power supply. This is a micro USB slot for connecting 5 volts using a USB cable and some headers for 3.3V and GND connections.
