Introduction:
The objective of this design is to integrate eight switches to allow four different power supplies to the breadboard busses; 5V 3A, 5V 3A, 3.3V 3A, and 3.3V 1A.

Creating Components:
Some of the components needed were not in the EAGLE nor the SparkFun Libraries. Thus, they had to be created with new footprints or existing ones in a personal library. Most footprints and symbols may be dowloaded from the internet. A good website for this is https://www.snapeda.com/home/, which was used in this project.



This library package was dowloaded from snapeda. The dimensions of the pads and footfrint were confirmed with the tutorial.


This package was created following the tutorial as well as the other capicitors needed. A personal library of all the created componenets was ready to use!


Schematic Layout:
After all of the componenets were acquired/created, the schematic was layed out.


The schematic was created following the tutorials, except for the switches. The switches were added via the concept of the tutorial.

PCB Board Layout:
The board was finally put together. Tutorial procedures were followed such as 40 mm wires, copper pour, and PCB design for application on a breadboard.


Final Design (show in a gerber file viewer)



The final design was to open space on the board for easier soldering (not necessary or ideal) and the capacitors were moved to be mounted on the bottom of the board.
