Introduction

We got tha powah! The Buck-Boost Converter is the latest breakout from SparkFun that allows you to fine tune the amount of power your project receives. It can take an input voltage of anywhere from 3-16V which can then be regulated to an output voltage between 2.5-9V. With the switch on the bottom of the board, you can set the common output voltages of 3.3V and 5V, but we've also broken out a custom setting that allows you to populate a resistor based on your custom voltage needs. What's more, we have broken out the GPIO pins along the top of the board for even more control. Get your boost on!
