Trabajo realizado

Actualicé la descripción del proyecto.
Definí el diagrama de arquitectura (Mermaid).
Integré CC pull-down (R1/R2), ESD D1, TVS D2, regulador U2 con C6/C7.
Coloqué U3 (ESP32-C3) y U4 (SHT45) en el esquema.

Tareas pendientes

Ajustar el tamaño del PCB (no automatizable).
Añadir condensadores de desacople C8/C9 junto a U3.
Añadir resistencias pull-up R3/R4 en SDA/SCL y conectarlas a +3V3.
Incorporar el header UART (pads de programación) y conectar TX/RX/GND.
Conectar +3V3 y GND a U3/U4; enlazar SDA y SCL entre U3 y U4.
Definir región de keepout de antena en el PCB.
Añadir test points y etiquetar nets en el esquema.
Ejecutar ERC y resolver avisos.

Tareas sin automatizar (marcadas CANT DO)

Cambiar tamaño del PCB.
Añadir C8 y C9 alrededor de U3.

Revisión de criterios de éxito

ERC limpio: pendiente.
Pull-ups I²C, pads UART, keepout de antena: faltan.
Sincronización con PCB 2D: pendiente.

Siguiente paso recomendado Completar el esquema (pull-ups, pads UART, desacoples faltantes y conexiones de net), luego correr ERC. Tras aprobación, sincronizar a PCB y revisar colocación en 2D.
