Overview

PCB TCC is an open-source printed circuit board by DaFrancoGui, from the DaFrancoGui/TCC repository on GitHub. It is a 2-layer board of 87.3 × 125 mm with 6 parts on 23 nets, routed with 232 tracks and 14 vias.

It is built around the ESP32-C6FH4, DS18B20 and MAX30102, with the MPU-9250 among its other parts. It belongs with the ESP32 and RISC-V boards of this library.

Instituto Federal de Santa Catarina

Plataforma vestível modular multissensor baseada no ESP32-C6

Repositório do Trabalho de Conclusão de Curso de Guilherme da Costa Franco, desenvolvido no Curso de Engenharia Eletrônica do Instituto Federal de Santa Catarina — Câmpus Florianópolis, sob orientação do Prof. Me. Leandro Schwarz.

O projeto integra, em uma plataforma embarcada única, interface gráfica circular sensível ao toque, relógio de tempo real e sensores biométricos, ambientais e inerciais. A contribuição central é a organização modular do firmware, com serviços compartilhados, tarefas independentes, inicialização não fatal e contenção funcional da ausência de sensores.

Hardware integrado

  • XIAO ESP32-C6;
  • Round Display for XIAO, com GC9A01A, CHSC6X e PCF8563;
  • MAX30102 para aquisição PPG e estimativas funcionais de frequência cardíaca e SpO₂;
  • DS18B20 para temperatura;
  • LTR390 para luz ambiente e ultravioleta;
  • MPU-9250/AK8963 para pedômetro e bússola;
  • placa protótipo autoral, invólucro impresso em 3D e bateria recarregável.

As avaliações têm alcance funcional e arquitetural. O repositório não atribui finalidade médica ao dispositivo, autonomia não medida nem precisão metrológica sem referência rastreável.

Reprodutibilidade

Para compilar, instale o ESP-IDF 5.5.1 e abra o atalho ESP-IDF PowerShell da instalação. No VS Code com a extensão configurada, use Ctrl+Shift+P → ESP-IDF: Open ESP-IDF Terminal. Confira idf.py --version e execute:

sh
cd Codigos/IDroid
python -m pip install -r tests/requirements-build.txt
idf.py reconfigure
idf.py build

O Component Manager baixa automaticamente a LVGL 8.3.11, já fixada no manifesto, e as demais bibliotecas. Em um projeto novo, adicione essa versão com idf.py add-dependency "lvgl/lvgl==8.3.11". O guia do firmware detalha instalação, ativação manual do terminal, dependências e gravação.

O caderno de ensaios relaciona procedimentos, instrumentos, arquivos de dados, scripts, figuras e limitações.

Questions

How big is the PCB TCC PCB?

It measures 87.3 × 125 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PCB TCC use?

6 parts, built around the ESP32-C6FH4, DS18B20, MAX30102 and MPU-9250. 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 PCB TCC KiCad files?

From the DaFrancoGui/TCC repository on GitHub, at the commit this page was made from: the board is Projeto_PCB/PCB_TCC.kicad_pcb and its schematic Projeto_PCB/PCB_TCC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PCB TCC design in my own project?

Its repository states no licence, so its author keeps all rights: ask DaFrancoGui before reusing the design.
