Course Lesson 4 of 10: Raspberry Pi Pico Expansion board for 4WD Smart Car Kit

Welcome to Lesson 4 of the Raspberry Pi Pico Smart Car course by Robojax, led by instructor Ahmad Shamshiri. This lesson is part of the structured 10-part series based on the SunFounder Raspberry Pi Pico 4-Wheel Drive Smart Car Kit.

In this video, the focus is on the expansion board—the key electronic interface that connects the Raspberry Pi Pico to all other components of the smart car. Understanding the layout and function of this board is critical before moving on to wiring and programming in future lessons.

What You’ll Learn

In this lesson, Ahmad provides an overview of the expansion board, explaining how it simplifies connections between the Raspberry Pi Pico and the car’s motors, sensors, lights, and other modules. The board serves as a central hub, enabling clean, reliable wiring and modular connections.

You’ll also learn:

• The general layout of the board

• How the Pico plugs into the expansion interface

• What the labeled pins and ports correspond to

While the video doesn't include code or assembly steps, it builds the theoretical foundation needed to wire and debug future components confidently.
