Questions
How big is the Senior design PCB?
It measures 128.6 × 80.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Senior design use?
135 parts, built around the RA8875L3N, 74HC4050D, M24C64-WMN6TP and PESD3V3S1UL. 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 Senior design KiCad files?
From the Rubeez1/GripLab_PCB repository on GitHub, at the commit this page was made from: the board is senior_design.kicad_pcb and its schematic audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Senior design design in my own project?
Its repository states no licence, so its author keeps all rights: ask Rubeez1 before reusing the design.
