Overview
Pcbcomando is an open-source printed circuit board by Serra-Rocketry, from the Serra-Rocketry/ignitor repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 60 × 58 mm with 14 parts on 41 nets, routed with 148 tracks and 22 vias.
It is built around the RA-02. Its parts include 5 connectors, 3 diodes, 2 capacitors, 2 resistors and 1 IC. It belongs with the RP2040 boards of this library.
Main components
1README
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.

Pinagem completa e BOM: hardware/README.md.
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 Pcbcomando PCB?
It measures 60 × 58 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcbcomando use?
14 parts, built around the RA-02. 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 Pcbcomando KiCad files?
From the Serra-Rocketry/ignitor repository on GitHub, at the commit this page was made from: the board is hardware/kicad/pcbignicao/pcbcomando/pcbcomando.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 Pcbcomando 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).
