Questions
How big is the AgatSpeechBoard PCB?
It measures 99.1 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AgatSpeechBoard use?
31 parts, built around the TL084 and L7905. 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 AgatSpeechBoard KiCad files?
From the sintech/AgatSpeechBoard repository on GitHub, at the commit this page was made from: the board is schematics/AgatSpeechBoard/AgatSpeechBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AgatSpeechBoard 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).
