Questions
How big is the Babelfish PCB?
It measures 72 × 43.4 mm and has 4 copper layers, 1.62 mm thick.
What parts does the Babelfish use?
101 parts, built around the RP2040, W25Q128JVSIQ, GT-USB-7010ASV and MAX3232IDR. 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 Babelfish KiCad files?
From the vvuk/babelfish repository on GitHub, at the commit this page was made from: the board is hardware/babelfish.kicad_pcb and its schematic hardware/babelfish.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Babelfish 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).
