  • Software: Arduino IDE 2.0+
  • Bibliotecas: ver docs/FIRMWARE.md

📖 Documentação

🎯 Funcionalidades

  • ✅ Aquisição de dados de empuxo e pressão em tempo real
  • ✅ Armazenamento em cartão SD com arquivos sequenciais
  • ✅ Controle local por botões (TARE e novo arquivo)
  • ✅ LED de status de gravação no SD
  • ✅ Comunicação (Serial, Bluetooth)
  • ✅ Calibração persistente da célula de carga

📊 Dados de Teste

Os dados de testes estáticos de motores específicos são armazenados no repositório dedicado: motor

Este repositório (thrust-stand) contém apenas o sistema de aquisição. Os dados coletados durante os testes devem ser commitados no repositório motor.

Questions

How big is the Teste estatico PCB?

It measures 92.1 × 81.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Teste estatico use?

11 parts. 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 Teste estatico KiCad files?

From the Serra-Rocketry/thrust-stand repository on GitHub, at the commit this page was made from: the board is hardware/teste_estatico/kicad/projeto kicad/teste_estatico.kicad_pcb and its schematic hardware/teste_estatico/kicad/projeto kicad/_restore_backup_2026-05-29T19-16-41-364/teste_estatico.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Teste estatico 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).
