🚀 Why It’s Ideal for Your Projects

• Double-sided construction — With copper pads on both sides and through-holes connecting them, this board gives you more wiring flexibility and cleaner layouts than single-sided boards.

• Standard spacing — The 0.1″ grid aligns with common DIP and header formats, allowing seamless use of Arduino shields, IC sockets, sensors and modules.

• Durable and professional quality — Made on FR-4 substrate with suitable copper weight and board thickness, it’s robust enough for soldering and repeated prototyping use.

🎯 Typical Applications

• Prototype circuit builds — Quickly lay out and wire new designs using the board as a base before committing to a custom PCB.

• Embedded development — Ideal for mounting microcontrollers, sensors and modules in breadboard-compatible layouts for testing or small runs.

• DIY electronics & hobby projects — Use for building custom controllers, breakout boards, or simple one-off circuits where a custom PCB is not required.

• Repairs or modifications — Useful for replacing damaged PCB sections or adapting existing hardware by soldering components directly to the proto board.
