About the Estacao de Ignicao (SMD) - LoRa 433 MHz PCB

Estacao de Ignicao (SMD) - LoRa 433 MHz is an open source ESP32 PCB design by Serra-Rocketry, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 85 × 70 mm, with 29 components from 24 distinct parts.

Its main chip is the SC0915, from the ESP32 family. Other key parts include the Ra-02 and PC817C. By type, the board carries 11 connectors, 7 resistors, 5 diodes, 3 ICs, 2 capacitors and 1 module.

It belongs with the rf & radio and power & battery designs in this gallery.

From the project

[Propulsion] Remote ignition system for rocket motors.

O sistema possui duas estacoes independentes conectadas por LoRa 433 MHz:

- Estacao de Comando: operada pelo usuario em area segura. - Estacao de Ignicao: fica proxima ao foguete e aciona o ignitor.

Pinagem da pcbignicaosmd` (footprint DIP-38):

1. Comando envia ARMCONFIRMED enquanto o botao e mantido. 2. Ignicao confirma com ACK e inicia contagem de 5 s. 3. Se houver ABORT ou perda de sinal > 500 ms, ciclo e cancelado. 4. Ao final da contagem, saida de ignicao ativa por 2 s. 5. Ignicao envia IGNITIONCOMPLETE.
