Questions
How big is the Ti92-reviceStable PCB?
It measures 205 × 113.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ti92-reviceStable use?
94 parts, built around the BAT54C. 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 Ti92-reviceStable KiCad files?
From the ccadic/TI92-revive repository on GitHub, at the commit this page was made from: the board is ti92-reviceStable/ti92-reviceStable.kicad_pcb and its schematic ti92revive/keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ti92-reviceStable design in my own project?
Its repository states no licence, so its author keeps all rights: ask ccadic before reusing the design.
