README
README.mdSerra Rocketry Ignitor
Sistema de ignicao remota para foguetes experimentais.
Visao Geral
Duas estacoes independentes se comunicam via LoRa 433 MHz:
| Estacao | Funcao | MCU |
|---|---|---|
| Comando | Operacao remota e seguranca | Raspberry Pi Pico |
| Ignicao | Acionamento do ignitor | ESP32-C3 SuperMini ou Raspberry Pi Pico |
Sequencia de Ignicao
- Operador segura o botao por 5 s.
- Comando transmite
ARM_CONFIRMEDcontinuamente. - Ignicao executa contagem regressiva (5 bipes).
- Rele aciona por 2 s.
- Ignicao envia
IGNITION_COMPLETE.

Regras de Seguranca
- Botao de ignicao deve ser momentaneo (sem trava).
- O comando precisa ser mantido pelos 5 s completos.
- Perda de sinal por mais de 500 ms deve abortar.
- Sempre usar carga dummy antes de ignitor real.
- Sempre conectar antena LoRa antes de energizar.
- Manter distancia minima de 10 m entre operador e foguete.

Questions
How big is the Pcbignicao smd PCB?
It measures 85 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcbignicao smd use?
36 parts, built around the RA-02, PRPC001SAAN-RC, PRPC002SAAN-RC and PRPC003SAAN-RC. 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 Pcbignicao smd KiCad files?
From the Serra-Rocketry/ignitor repository on GitHub, at the commit this page was made from: the board is hardware/kicad/pcbignicao/pcbignicao_smd/pcbignicao_smd.kicad_pcb and its schematic hardware/kicad/pcbignicao/pcbcomando/alimentacao.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcbignicao smd 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).
