ECE445L Final Project is an open-source printed circuit board by DylanMeeks, from the DylanMeeks/ece445l-lab7-10 repository on GitHub. It is a 2-layer board of 152.4 × 127 mm with 585 parts on 221 nets, routed with 2,966 tracks and 258 vias.
It is built around the SN74LVC1T45DBVRE4, SK6805E-J and BAT54C. Its parts include 343 connectors, 125 diodes, 88 capacitors, 24 resistors and 3 ICs.
The typical explanation for the repo structure. Lab specific instructions can be found further below.
The hw folder should contain your schematic and board files for your PCB or
circuits. In labs 1-5 and 10, you will be creating schematics for your circuit
in KiCad.
The sw folder should contain your application firmware and software written
for the lab. The sw/inc folder contains firmware drivers written for you by
Professor Valvano. Feel free to write your own (in fact, in some labs, you may
be required to write your own).
You can place any other source files in the sw folder. TAs will look at the
files you create and/or modify for software quality and for running your
project.
A couple files are provided in the Resources folder so you don't have to keep searching for that one TI document. Some of them are immediately useful, like the TM4C datasheet. Others may be useful for your final project, like the TM4C_System_Design_Guidelines page.
We will extensively use Git and Github for managing lab projects. This makes it easier for TAs to grade and help debug the project by allowing us to see commit histories, maintain a common project structure, and likewise, it makes it easier for students to collaborate with partners, merge different codebases, and to debug their work by having a history of commits.
Two common ways of using Git and Github are Github Desktop and the command line. Tutorials are also abundant on the net for you to peruse. We've provided a cheatsheet for git in the Resources folder.
It is highly recommended to make the most out of Git, even if you've never used it before. Version control will save you a lot of suffering, and tools like Git or SVN are ubiquitous in the industry.
A gitignore file is added to the root of this repo that may prevent specific files from being tagged to the repo. This are typically autogenerated output files we don't care about, but sometimes other stuff (like .lib files) falls through that we want. Feel free to modify if necessary.

It measures 152.4 × 127 mm and has 2 copper layers, 1.6 mm thick.
585 parts, built around the SN74LVC1T45DBVRE4, SK6805E-J and BAT54C. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the DylanMeeks/ece445l-lab7-10 repository on GitHub, at the commit this page was made from: the board is hw/ECE445L_Final_Project_Bottom/ECE445L_Final_Project.kicad_pcb and its schematic hw/ECE319K_Starter/ECE319K_Starter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask DylanMeeks before reusing the design.
