Electronics learning bench with starter components and microcontrollers

Future training path

Learn electronics by fixing real failures.

The future PCBVault training path will take builders from ESP32 and Arduino debugging to reliable prototypes, KiCad, BOM cleanup, and PCB handoff.

Curriculum direction

Built around the failures students and makers actually face.

Module 1

Debugging Basics

Serial monitor, minimal sketches, wiring sanity, and symptom-to-cause thinking.

Module 2

ESP32 and Arduino

Upload issues, WiFi, I2C, safe pins, boot failures, and module isolation.

Module 3

Power and Loads

Brownouts, SIM800L, relays, servos, motors, regulators, grounding, and noise.

Module 4

Sensors and Displays

OLED, LCD, DHT, HC-SR04, I2C scanner, address conflicts, and data validation.

Module 5

KiCad and PCB

Schematic cleanup, footprints, connectors, test points, Gerbers, and first-board checks.

Module 6

Project Handoff

BOM, documentation, enclosure notes, test plan, and prototype-to-product thinking.

Before training opens

Use the tools and guides as the free foundation.

These tools are the beginning of the course material: power estimation, I2C scanning, safe pin selection, and reliability scoring.
