Power Supply and DC Regulators on PCB for MCU

Introduction:
In this homework assignment we setup vim and get familar with the new software Vivado.

Materials and Methods:
Using EaglePCB software: Design the power module on the PCB is the first step of the PCB design. You must find the technical parameters of the chips/parts used on the PCB and estimate the current/voltage needed by the system. If the power input is 110 VAC only, you'll need to build a AC-DC converter (a transformer) on the PCB. However, there are many commercial AC-DC adaptors on the market. We just need to pick up a competent one which has enough power to support the loads on the PCB to provide a DC voltage to the board and being regulated to low voltage to supply the MCUs

Results:

Task 1: Create all the componets and libraries needed for the PCB design


Figure 1: Shows Capacitor Labrary created to make the project


Figure 2: Shows the diode created


Figure 3: Shows the Inductor Library that was created for the project


Figure 4: Shows two miscellaneous componets that needed to be created


Figure 5: Shows the Library of Power Componets that were needed to be created

Task 2: Create a schematic of the componets and finish the board layout


Figure 6: Shows the Schematic of the componets together with only warnings and shows that the board and schematic match.


Figure 7: Shows the Board of the design with no DRC errors and fully connected

Discussion:
This Assignment was really interesting to complete and work through. Having done nothing like this before I found it really interesting and kept messing around trying to make the layout nice and uniform. This made it take more time to complete. The thing I has most trouble with was I didnt measure the breadboard before I started to do the layout and route the wires. This made the board way too big. So once I got the measurments I needed I had to rethink how I was going to nest the componets together inorder to have good wires. Once that was done it was straight forward to finish the rest of the homework.
