Adjustable portable power supply with charging function

Overview

1. The battery input is boosted to power the LM1117 and LM35. My boost module, adjusted to a 15V adjustable power supply, can output up to approximately 13V.
2. A master switch is included for easy shutdown when not in use, reducing power consumption on the boost module. The master switch must be turned on when charging the charging module is connected.
3. When attaching the battery to the back, a piece of cardboard can be added to prevent component pins from scratching the battery.
