A compact prototyping shield designed specifically for the Arduino Pro Mini. When your project needs just a bit more space for external circuitry, this shield adds 38 unconnected plated through-holes (PTHs) in a form factor that matches the Pro Mini.
The shield connects to the top four pins on each side of the Mini (GND–TXO and VCC–RAW) and includes small power buses for VCC, GND, and RAW. Serial pins are also broken out on the shield for easy access.
Key Features
- 38 Prototyping PTHs – Plenty of space for custom circuitry
- Pro Mini Form Factor – Matches the compact footprint of the Arduino Pro Mini
- Power Buses – Dedicated VCC, GND, and RAW bus lines
- Serial Breakout – Serial pins broken out for convenient access
Ideal For
- Expanding Arduino Pro Mini projects with custom circuitry
- Compact prototyping where space is limited
- Adding external components without a separate breadboard

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
