319KFinalProject

For our final project, we recreated Space Invaders in C, using a custom-designed PCB and an MSPM0G3507 microcontroller. The game integrates hardware components including buttons, a slide potentiometer, and a DAC to control gameplay elements. We designed, printed, and assembled the PCB ourselves, and developed the game logic and graphics from scratch to run on the microcontroller.

Questions

How big is the MVM833 PCB?

It measures 114.3 × 88.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the MVM833 use?

46 parts, built around the TSOP31438 and ULN2003BD. 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 MVM833 KiCad files?

From the SiddharthaG09/319KFinalProject repository on GitHub, at the commit this page was made from: the board is PCBSchematics/MVM833.kicad_pcb and its schematic PCBSchematics/MVM833.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the MVM833 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
