PCB Schematic Design Guide

“Schematic + PCB”.

Plasser symboler:

ESP32 38-pin header-breakout (i Flux-biblioteket: “ESP32 DevKitC” eller generisk 2×19 header). I verste fall lager du to 1×19 headers (2.54 mm) og merker pinnene.

I²C OLED header: 1×4 pin-header (VCC, GND, SCL, SDA).

LED-seksjon: 3× LED (THT 3 mm) + 3× motstander (THT ¼ W).

Valgfrie I²C pull-ups: 2× 4.7 k (SDA→3V3 og SCL→3V3), DNP i BOM.

Plan

Using Knowledge Base Tool.

Jeg plasserer symboler og footprints for ESP32‑header, I²C OLED‑header, 3× LED med seriemotstander, samt valgfrie I²C pull‑ups.

ESP32: legg til ESP32 DevKitC eller 2x19 Header; ev. to 1x19 Header og merk pinnene.
I²C OLED: Pin Header 1x4 (VCC, GND, SCL, SDA).
LED‑seksjon: 3× LED 3mm THT + 3× Resistor THT 1/4W i serie.
Pull‑ups: 2× 4.7k Resistor THT, merkes DNP.

Generic Capacitor
A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
