2 layers75 × 50 mm Traducteur Morse v3, the printed circuit board in 3D

Traducteur Morse v3

1st year end-of-semester project with encompasses Morse language and communications. We made a Morse translator from scratch, working on both hardware and software by designing a PCB in KiCad and writing code in C in STM32CubeIDE. You can find all the PCB files, code and datasheets in this repository.

Overview

Traducteur Morse v3 is an open-source printed circuit board by Kirth-lab, from the Kirth-lab/Morse_Translator_Project repository on GitHub, published under the MIT licence. It is a 2-layer board of 75 × 50 mm with 40 parts on 78 nets, routed with 452 tracks and 214 vias.

It is built around the BU33SD5WG-TR and PTS645TM952LFS. Its parts include 11 capacitors, 8 resistors, 7 connectors, 4 diodes and 2 ICs. It belongs with the STM32 boards of this library.

Morse Translator Project

Made by melluche and Kirth-lab, 1st-year students at ENSEA. The Morse Translator project allows you to translate a Morse coded message by typing your message in the keypads. It also works in the opposite way : you can code your message in Morse language, and the alphabet coded message will show in the screen.

In the repository, you may find all the PCB files, code and datasheets.

Objectives :

Translate a Morse coded message to an alphabet coded message by typing the touch "." and "-" on the keypads. After coding, the message will be shown on the screen and you will be able to read it.
Translate an alphabet coded message to a Morse coded message using the keypads. After typing, a buzzer will play the bips of the message, and a LED will blink at the same time.

Questions

How big is the Traducteur Morse v3 PCB?

It measures 75 × 50 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Traducteur Morse v3 use?

40 parts, built around the BU33SD5WG-TR and PTS645TM952LFS. 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 Traducteur Morse v3 KiCad files?

From the Kirth-lab/Morse_Translator_Project repository on GitHub, at the commit this page was made from: the board is PCB_Design/KiCad_files/Traducteur_Morse_v3.kicad_pcb and its schematic PCB_Design/KiCad_files/Traducteur_Morse_v3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Traducteur Morse v3 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).
