You are going to need a regulated power supply for many electronics projects. Thanks to the snapVCC, you will have an easier time powering your creations. It fits right on a 9V battery and gives you 3.3V or 5V power when you need it. Here is the neat part: you can charge a phone with a snapVCC.
snapVCC uses a buck converter for efficient regulation. You can switch between 3.3V and 5V by just switching a jumper. Like what you see? You may want to support the project here.
