Why Choose SunFounder Expansion Boards?

Prototyping with a Raspberry Pi often involves messy wiring and unstable connections. SunFounder Raspberry Pi expansion boards solve this by providing robust, clearly labeled interfaces. Our T-Extension boards and GPIO breakout modules are engineered with precision to fit standard breadboards, minimizing short circuits and connection errors. Unlike generic expansion boards, ours come with clear pinout documentation and examples, making them the preferred choice for STEM education and rapid prototyping.

What Can You Build?

○ Clean Prototyping Setup: Use a T-Cobbler expansion board to extend the 40-pin GPIO to a breadboard, allowing you to build complex circuits without soldering.
○ Industrial Controllers: specific Screw Terminal expansion boards provide secure wire hold, perfect for installing Raspberry Pi in permanent control cabinets or home automation systems.
○ Sensor Hubs: Connect multiple sensors easily using a multi-functional IO expansion board, reducing the clutter of jumper wires.

Frequently Asked Questions

○ What is the difference between a HAT and an expansion board?
A HAT (Hardware Attached on Top) sits directly on the Pi, while a Raspberry Pi expansion board often refers to breakout boards (like T-Cobblers) that extend the pins to an external area or convert the interface for easier wiring.
○ Are these expansion boards compatible with Raspberry Pi 5?
Yes, the 40-pin GPIO header standard has remained consistent. Our Raspberry Pi expansion boards and breakouts work seamlessly with Raspberry Pi 5, 4 Model B, and 3B+.
○ Do I need to solder the expansion boards?
Most of our expansion boards come fully assembled or require minimal assembly (like attaching standoffs), making them plug-and-play for your projects.
