Questions
How big is the Mind Speak (Main Board) PCB?
It measures 70 × 55 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Mind Speak (Main Board) use?
89 parts, built around the CDBU0130L, LIS3DH, LP5907MFX-3.3 and SN74LVC1G32DCKR(AT). 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 Mind Speak (Main Board) KiCad files?
From the Mo3tasemO/Graduation_Project repository on GitHub, at the commit this page was made from: the board is Hardware_Design/Mind_Speak_(Main_Board)/Mind_Speak_(Main_Board).kicad_pcb and its schematic Hardware_Design/Mind_Speak_(Dongle_Board)/Mind_Speak_(Dongle_Board).kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mind Speak (Main Board) design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mo3tasemO before reusing the design.
