When developing electronic projects, the power supply is one of the most important part of whole project and there is always need of multiple output voltage power supply. This is because different sensors need different input voltage and current to run efficiently. In this scenario, a power supply which can output multiple voltages becomes very important. There are options that an engineer can use for external power supply like RPS (regulated power supply) or AC adaptors but then multiple power supplies will be needed and the whole system will become bulky.
So today we will be designing a Multipurpose Power Supply. The Power Supply will be an Arduino UNO Power Supply Shield which will output multiple voltage range such as 3.3V, 5V and 12V. The Shield will be a typical Arduino UNO shield with all pins of Arduino UNO can be used along with extra pins for 3.3V, 5V, 12V and GND. Here the PCB is designed on the EasyEDA PCB Designer and manufactured by PCBGoGo.
