SBC MicroTrainer — Version 1

A Pocket-Sized Training Tool

I designed this SBC MicroTrainer — Version 1 Business Card as a hands-on teaching tool that goes far beyond a traditional business card. Instead of just printed contact information, it’s a fully functional electronic circuit board designed to help students explore the foundational concepts of series and parallel circuits.

This card combines electronics education and design creativity—a compact, visual way to demonstrate how current and voltage behave in different circuit configurations.

🔌 Powering the Board

This switch on the top left of the board is called the master switch — it controls power to the entire board.
To turn the board on, slide the switch to the right.
When the switch is off, no current flows through the board.

Once the board is powered, you can:

• Explore the components that make up a simple circuit — power, ground, switch, resistor, and LED

• Observe how LEDs behave in both series and parallel circuits

• Measure voltage and current at different points

• See how resistance affects circuit behavior

• Practice using your multimeter correctly on a real circuit

The SBC MicroTrainer gives you a safe way to explore and measure what’s really happening in an electrical circuit — the same principles you’ll find in a vehicle’s wiring system.
