DC-DC 1.8V-5V to 3.3V, Booster and Buck Power, Modules

Is your project board going to require a 3,3V consistent power supply? Here is the most cost-effective answer to your problem...! Buy this DC-DC 1.8V-5V to 3.3V Booster and Buck Power Modules in a small size (11 x 7 mm) that provides a consistent 3.3V DC output with an input supply range of 1.8 to 5 VDC. The buck-boost module steps up the voltage when the input is less than 3V and steps down the voltage when the input is greater than 3.3V, hence the name. Circuit Diagram:
