README
README.mdSingle Board Computer
CPGR4253 Microcomputer Design is not as much a technical course at LeTourneau University as it is a design project. The goal of the course is to design a functioning Single Board Computer with the following requirements:
- A microprocessor
- At least 64Kib RAM
- ROM memory to store monitor program
- Serial connection to external terminal
This repository is the container of all digital files supporting this project.

Questions
How big is the SBC Circuit PCB?
It measures 127 × 114.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SBC Circuit use?
91 parts, built around the FT230XS-R, LD1117AV33, MC34064P-5G and AOI21357. 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.
Where can I download the SBC Circuit KiCad files?
From the richardhoman99/Single-Board-Computer repository on GitHub, at the commit this page was made from: the board is SBC Circuit/SBC Circuit.kicad_pcb and its schematic 11x17 Schematic/11x17 Schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SBC Circuit design in my own project?
Its repository states no licence, so its author keeps all rights: ask richardhoman99 before reusing the design.
