# HBOX Watchdog V3 (PROD) — Pinout de arneses y conectores
|
|
|
|
Tarjeta: V3 (EinarBoard 1.0, `kicad/hbox-watchdog-v3-PROD`).
|
|
|
|
!!! note "Solo V3 — para V5.6 usa [Pinout V5.6](../hardware/v56-pinout.md)"
|
|
Este pinout es de la tarjeta V3 (registro congelado tal como se fabricó). La V4 comparte conectores con la V5 salvo lo indicado en el [manual V4](../manuales/manual-tarjeta-V4.md).
|
|
|
|
Generado automáticamente desde la netlist de la PCB (independiente de la colocación). `GND` = plano de tierra de la tarjeta (In1.Cu); se omite su lista completa de pads. Las nets de potencia van marcadas ⚡ para elegir el calibre del cable.
