Jaycar Arduino Compatible DC Voltage Regulator Module – 4.5–35V Input, 3–34V Adjustable Output

Your project needs 7.4V and your supply's sitting at 12. This module takes anything from 4.5 to 35VDC and dials it down to exactly the voltage you need, anywhere between 3 and 34V. Turn the multi-turn potentiometer until you hit the number. Done. Max output current is 2.5A, which covers most hobby builds, sensor arrays, and prototyping loads without breaking a sweat. No soldering. Just set the pot, plug in your board, and get on with the build
