# Breadboard to PCB

Take three working circuits from the breadboard to a finished board: the schematic, footprints, placement, routing, design rules, and what a board house needs.

What you will build

## 2 projects, built step by step

6 lessons in 3 chapters, about 3 hours on a simulated breadboard. Free, in your browser, every step checked by the simulator.

Chapter 1 project

### Footprints

Every part becomes copper pads and holes of the right size and spacing: read the four footprints of a USB to 3.3 V board, their drills, and where a footprint and the real part disagree.
Open it in the simulator

Chapter 2 project

### Design rules

What a board house can make: track width, spacing, drill, annular ring and edge clearance, the DRC that checks them, and rules broken on purpose to see what it says.

The map

## Chapter by chapter

Each lesson opens when the one before it is done, and each chapter ends in a project.

Chapter 1

## From circuit to board

Read the schematic, and see each part become its footprint.

Open 204 XP

### The schematic

Before any board, the circuit as a drawing: symbols instead of parts, nets instead of wires, and a 7805 supply read from its schematic, dropout included.

Chapter 2

## Lay it out

Place the parts, route the copper, and pass the design rules.

Locked 166 XP

### Placement

Where the parts go decides how hard the routing is: the ratsnest of a 555 blinker, the placement rules that keep it short, and parts dragged and turned by hand.

### Routing

Turn the ratsnest into copper: a power track drawn by hand, two layers and a via, the autorouter for the rest, and why a power track is twice as wide.

## Ready to make

What Gerbers and a BOM are, read off a finished board.

### Gerbers and the BOM

What a board house actually receives: the Gerber layers, the drill file and the bill of materials, read off a finished USB to 3.3 V board by looking at it as made.

All 6 lessons, in order, each with what it covers. Any of them opens in the editor right away.

Chapter 1

### From circuit to board

- Footprints Every part becomes copper pads and holes of the right size and spacing: read the four footprints of a USB to 3.3 V board, their drills, and where a footprint and the real part disagree.

Chapter 2

## The next course on your track

Breadboard to PCB is part of the electrical track, a ladder of courses from zero to expert.

Next course

### Power electronics

Advanced: switches, inductors and heat: buck and boost converters from loose parts, PWM, MOSFET drivers, H bridges, efficiency, and a regulated supply you set from its formula.

Track

### Electrical track

Current and voltage you can see, then transistors, op-amps, filters, power and PCBs. Every circuit runs in a real circuit simulator in your browser.

Kits

## Build it on your bench too

Every lesson runs in the simulator with nothing to buy. When you want the real thing, these kits have the parts.

Have a kit already?

### Find your kit

Pick the starter kit you own and run every lesson in its manual with the same parts on the same pins.

Questions

## About Breadboard to PCB

Is Breadboard to PCB free?

Yes. All 6 lessons of Breadboard to PCB are free and run in your browser, with nothing to install and no parts to buy before you start.

Do I need any parts?

No. Every circuit is built on a simulated breadboard, and the simulator checks each step as you go. When you want to build it for real, the same parts and wiring work on a real bench.

How long does Breadboard to PCB take?

About 3 hours: 6 lessons in 3 chapters, each one a few short steps. Your progress is kept, so you can stop after any lesson and pick up where you left off.

What will I build?

Each chapter ends in a project that puts it together: Footprints and Design rules.

Where do I start?

With "The schematic", and each lesson builds on the one before it. New to circuits? Electronics basics is the course that starts from zero.
