Questions
How big is the Glyphblaster PCB?
It measures 53.6 × 72.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Glyphblaster use?
25 parts, built around the SN74LVC244AN, SS14 and AO3400A. 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 Glyphblaster KiCad files?
From the dbalsom/GlyphBlasterPCB repository on GitHub, at the commit this page was made from: the board is glyphblaster.kicad_pcb and its schematic glyphblaster.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Glyphblaster design in my own project?
Its repository states no licence, so its author keeps all rights: ask dbalsom before reusing the design.
