Questions
How big is the Hack fft PCB?
It measures 196 × 104 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hack fft use?
611 parts, built around the CH340C, ESP32-PICO-D4-V2, ICS-43434 and SPX3819S. 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 Hack fft KiCad files?
From the hack-apollo/hack_spectrum repository on GitHub, at the commit this page was made from: the board is hardware/hack_fft.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hack fft design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
