Flexible Single Sided ProtoBoard (18x30cm)

Flexible Single Sided ProtoBoard (18×30cm) is a thin, bendable prototyping PCB designed for rapid circuit development and compact electronics integration. Built with high‑quality FR‑4 material and a standard 2.54mm (100mil) hole grid, this electronics prototyping board supports both DIP and SMD component soldering while maintaining excellent structural flexibility. With an ultra‑slim 0.4mm profile and 1mm plated apertures, the flexible circuit board can be trimmed, shaped, and bent to match custom project enclosures or irregular layouts. Such adaptability makes the prototyping platform suitable for compact embedded systems, wearable electronics, robotics prototypes, and experimental circuit design.

Ultra‑Thin Flexible FR‑4 Construction

This bendable prototyping PCB uses high‑quality FR‑4 substrate with a thickness of only 0.4mm, allowing gentle flexing without damaging traces or solder joints. The slim structure enables installation in curved surfaces or tight mechanical spaces where standard rigid protoboards cannot fit. Designers creating wearable electronics, compact robotics modules, or custom enclosure circuits benefit from the ability to slightly bend the board while maintaining electrical reliability.

Standard 2.54mm Prototyping Grid

The single‑sided proto board features a universal 2.54mm (100mil) hole spacing and 1mm apertures, supporting common DIP packages and many SMD soldering techniques. Such compatibility ensures straightforward integration with breadboard‑style circuit layouts and popular development hardware including Arduino controllers and compact embedded boards. The familiar prototyping grid allows quick migration from breadboard experiments to more durable soldered circuits.

Cuttable and Shape‑Customizable Design

The large 18×30cm flexible prototyping panel can be easily trimmed into smaller sections to match specific circuit requirements. Makers and engineers can cut custom shapes or smaller boards directly from the panel, optimizing material usage during iterative hardware development. This customizable prototyping substrate speeds up experimentation and simplifies circuit layout adjustments during early‑stage product design.

Such characteristics make the flexible prototyping platform suitable for quick circuit experiments, compact robotics electronics, DIY wearable devices, and creative maker projects. Example builds include projects like Make a shiny dice for monitoring battery capacity, combining modules such as the Gravity: I2C 3.7V Li Battery Fuel Gauge and the Beetle - The Smallest Arduino to create compact custom hardware on a cut‑to‑size prototyping surface.
