Maximize your circuit designs with our 233mm x 120mm Universal Prototype PCB Board. As one of the largest formats in our dot-matrix series, this board is engineered for engineers and makers who require extensive surface area for complex, high-component-count projects. Featuring a standard grid layout with precision-drilled, tinned holes, this board provides the stability and space needed for permanent industrial prototypes and sophisticated DIY electronics.
Massive Prototyping Surface: The extra-large 233mm x 120mm footprint is ideal for full-scale system boards and multi-stage analog or digital circuits.
Double-Sided Tinned Pads: Features high-quality tinned copper dots on both sides, allowing for complex multi-layer wiring and flexible component mounting.
Integrated Bus Rails: Designed with continuous contact strips along the top and bottom edges, simplifying power distribution and ground busing across the entire board length.
Professional Coordinate Grid: Includes clearly printed alphanumeric markings (A–V and 1–90+) to assist in accurate component placement and rapid circuit debugging.
High-Grade FR-4 Substrate: Built on a robust, heat-resistant base that prevents warping and pad delamination even during intensive soldering sessions.
The HS-09 series prototype board is the ultimate solution for large-scale hardware development. Its tinned finish ensures excellent solder flow and prevents oxidation, maintaining long-term electrical reliability. It is the preferred choice for building custom rack-mount equipment, industrial controller interfaces, and educational training modules.
Dimensions: 233mm x 120mm.
Can I use this for high-voltage projects?
While the substrate offers excellent insulation, always ensure proper trace spacing (creepage and clearance) when designing high-voltage circuits on universal dot-matrix boards.
Is it easy to mount in a standard enclosure?
Yes, the board features pre-drilled mounting holes in the corners, making it easy to secure with standard M3 standoffs or screws.
Can the pads handle repeated soldering?
Absolutely. These boards use high-quality tinned copper pads designed to withstand the heat of professional soldering and desoldering without lifting.
