Questions

How big is the E TKT PCB?

It measures 99.6 × 76.2 mm and has 6 copper layers, 1.6 mm thick.

What parts does the E TKT use?

158 parts, built around the ESP32-WROOM-32, FT231XS-R, B3FS-1000 and BSS138LT3G. 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 E TKT KiCad files?

From the hacklabkyiv/E-TKT repository on GitHub, at the commit this page was made from: the board is _electronic/KiCad/e-tkt.kicad_pcb and its schematic _electronic/KiCad/boot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the E TKT 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).
