\section{Identifica cada pieza ANTES de conectar}
|
|
\label{sec:identifica}
|
|
|
|
Esta sección es el \textbf{catálogo visual} del kit: cada módulo y componente dibujado
|
|
\textbf{como se ve de verdad}, con el nombre de cada patita y a dónde va. Las tablas de los
|
|
bloques (sección~\ref{sec:bloques}) te dicen \emph{qué} conectar; esta sección te enseña
|
|
\emph{dónde está} cada patita. Tres reglas de oro:
|
|
|
|
\begin{itemize}
|
|
\item \textbf{Confía en lo impreso, no en la posición.} Los módulos chinos cambian de un
|
|
lote a otro; los nombres serigrafiados (IN+, OUT$-$, B+, SDA\ldots) son los que valen.
|
|
Si el rótulo está por debajo, voltea el módulo y anótalo con marcador por arriba.
|
|
\item \textbf{En caso de duda, multímetro.} Continuidad (la escala que pita) para saber qué
|
|
está unido con qué; voltaje DC para verificar una fuente ANTES de conectarla a lo demás.
|
|
\item \textbf{Nada se conecta con la fuente energizada.} Cablea, revisa contra el dibujo,
|
|
revisa la polaridad, y hasta entonces enciende.
|
|
\end{itemize}

\begin{helgennotice}[Checklist antes de energizar CUALQUIER bloque]
|
|
\begin{itemize}
|
|
\item Rieles: rojo $=$ 5\,V, azul $=$ GND, en \textbf{toda} la guía. Nada de excepciones.
|
|
\item Electrolíticos: franja al GND. Diodos: banda como diga la tabla. Transistores:
|
|
cara plana como en el dibujo (sección~\ref{sec:transistores}).
|
|
\item Multímetro en continuidad: pita GND$\leftrightarrow$GND, \textbf{no} debe pitar 5\,V$\leftrightarrow$GND.
|
|
\item Fuentes ajustables (LM2596 / MT3608): voltaje medido y ajustado \textbf{en vacío} antes de conectar su salida.
|
|
\item \textbf{USB del Blackpill y riel 5\,V: nunca al mismo tiempo.} El pin \texttt{5V} de la
|
|
tarjeta está unido \emph{directo} al USB (sin protección). Para flashear: desconecta el
|
|
riel MAIN5V del pin \texttt{5V}, flashea por USB, desconecta el USB y reconecta el riel.

Pon la tarjeta \textbf{con el USB-C hacia arriba y los componentes hacia ti}. Para confirmar

que no la tienes volteada: la esquina superior \textbf{izquierda} dice \texttt{VB} y la

superior \textbf{derecha} dice \texttt{B12} (los nombres están serigrafiados junto a cada pin
|

— gira la tarjeta hasta que coincida con el dibujo). Los pines rellenos de color
