Overview

E TKT is an open-source printed circuit board by andreisperid, from the andreisperid/E-TKT repository on GitHub, published under the MIT licence. It is a 4-layer board of 99.6 × 76.2 mm with 110 parts on 99 nets, routed with 606 tracks and 464 vias.

It is built around the ESP32-WROOM-32, FT231XS-R and B3FS-1000, with the BSS138LT3G, SS8050 and AZ1117CH-3.3TRG1 among its other parts. It belongs with the retro computing and games boards and the ESP32 boards of this library.

E-TKT: anachronic label maker

Andrei Speridião - 2022 - andrei.cc

An open source label maker that fuses together both old and contemporary technology to create something as ubiquitous as... EMBOSSED LABELS!


By combining simple and widely available embossing tapes in a reliable mechanism with modern connectivity, E-TKT rescues a would-be future that did not happen, and at the same time gets rid of the dependence on proprietary cartridges, which are environmentally impacting & expensive.

how does it work?

An ESP32 commands the label production and also serves an on demand web application (local) to any device connected in a local network.

Neither internet is needed, nor installing any app.


documentation

It's now much more detailed, so I've moved it to a dedicated page.

If you ever build one, I would love to know ;)

And if you'd like, donations are more than welcome 😍

Questions

How big is the E TKT PCB?

It measures 99.6 × 76.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the E TKT use?

110 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 andreisperid/E-TKT repository on GitHub, at the commit this page was made from: the board is _electronic/e-tkt.kicad_pcb and its schematic _electronic/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).
