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 Converter Power Module 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.
- Input Voltage: 1.5V to 5V DC
- Output Voltage: 3.3V DC
- Dimensions (L x W)mm: 11 x 7
- 1 x DC-DC 1.8V-5V to 3.3V Boost and Buck Power Module
