2pcs Universal PCB 7×9 Dot Type

A Universal PCB 7×9 Dot Type (also called 7×9 cm dot matrix prototyping board or perfboard) is a general-purpose printed circuit board used for prototyping electronic circuits.

🔧 Key Features:

FeatureDescriptionSize7 cm x 9 cm (2.75 in x 3.54 in)MaterialUsually FR-4 fiberglass or phenolic paperHole Pitch2.54 mm (0.1 inch), compatible with standard DIP componentsHole LayoutDot type means each hole is isolated (not connected to adjacent holes)Copper SideUsually one-sided with copper pads around holes (sometimes double-sided)

🛠️ Usage:

• Solder through-hole components like resistors, ICs, and capacitors.

• Create point-to-point wiring using jumper wires or solder bridges.

• Custom circuit layout without needing a custom PCB.
