9 units and 41 lessons that start at voltage and current and finish at controlled impedance and power integrity. Plain English, no signup, no fluff.
Everything else builds on these ideas. Get comfortable with voltage, current, and resistance and the rest of electronics gets much easier.
Passive components handle energy without amplifying it. They make up most of any board, and they’re the parts you’ll pick and size yourself.
Active components use a small signal to control a bigger one. That single trick is what lets circuits amplify and compute.
A handful of rules let you work out the voltages and currents anywhere in a circuit before you build anything.
Digital circuits treat voltage as just two states. All of computing is built on top of that one idea.
Good power and grounding quietly decide whether a design is reliable. Most flaky boards trace back to these basics.
A PCB is a circuit made real in copper and fiberglass. These are the concepts every layout is built from.
Once the design is done, a specific set of files and steps turns it into real, working hardware.
Open unit 08At high speeds and high power, wires stop behaving like simple connections. These disciplines keep complex boards working.
9 units of theory are worth more once you have drawn something real. ProtoFlow is free to start.
