Shop Expansion Boards & Shields by Type

Our expansion board and shield range may include products such as:

• Arduino compatible shields: Add-on boards for Arduino-style boards, including prototype shields, terminal shields, sensor shields and I/O expansion boards.
• ESP32 and ESP8266 expansion boards: Breakout boards, terminal adapters and expansion boards for ESP development boards and compact WiFi modules.
• D1 Mini shields: Compact expansion boards designed for D1 Mini compatible ESP8266 projects.
• Terminal adapter boards: Screw terminal expansion boards that make wiring sensors, relays, power and I/O connections easier.
• Prototype shields: Boards that allow custom circuits to be built directly onto or alongside a development board.
• Breakout boards: Adapter boards that convert small, difficult or specialised pin layouts into easier-to-use headers or terminals.

Expansion Boards for Arduino, ESP32 & Microcontroller Projects

Expansion boards and shields are useful when a development board needs extra wiring points, easier terminal connections, additional I/O, or a more convenient layout for prototyping. They are commonly used in sensor projects, relay control systems, automation prototypes, test rigs, display projects, data logging and embedded electronics builds.

Some expansion boards are designed for a specific board or module, while others are more general-purpose. Always check the board compatibility, pin spacing, header layout, voltage, mounting holes and whether soldering is required before ordering.

Shields, Breakout Boards & Terminal Expansion Boards

Shields usually plug directly into a development board and add a specific layout or function. Breakout boards make small modules easier to connect, while terminal expansion boards make wiring more secure for projects that use sensors, relays, power connections or external devices.

Frequently Asked Questions

What is an expansion board or shield?

An expansion board or shield is an add-on board that connects to a development board or module to provide extra wiring points, terminals, prototype space or additional functionality.

Do you sell Arduino compatible shields?

Yes. AuscomTech stocks Arduino compatible shields and expansion boards depending on current availability, including prototype shields, terminal shields and I/O boards.

Do ESP32 and ESP8266 modules need expansion boards?

Not always, but expansion boards can make ESP32 and ESP8266 projects easier by adding screw terminals, standard header spacing, extra power connections or a more convenient wiring layout.

What is the difference between a shield and a breakout board?

A shield usually plugs into a development board and follows that board’s layout. A breakout board adapts a small module or connector into easier-to-use pins, headers or terminals.

Can you help me choose the right expansion board?

Yes. If you are unsure which expansion board suits your project, contact AuscomTech with your controller board model, module type, pin spacing, wiring needs and any photos of the parts you want to connect.
