Project: 5V to 3.3V Converter Module

Course Overview:

A lot of microcontrollers and sensor modules require 3.3V for powering, and you can’t get that from the usual voltage source like a battery or USB. Luckily there is a component called LD1117V33, a low drop voltage regulator able to provide 3.3V from any voltage source between 4.75 and 10 V.

In this project, you'll build a converter module where you can plug in 5V on one side, for example from a USB source, and get 3.3V out on the other side.

Finished 5V to 3.3V converter module
