The Prototype Soldering Board – 10 × 15 cm is a versatile prototyping PCB designed for building and testing custom electronic circuits after initial development on a solderless breadboard. Each pad on the board is electrically isolated, allowing users to create custom routing and solder connections as required. The board supports through-hole components and standard 2.54 mm spacing for compatibility with common electronic modules and headers. Suitable for DIY electronics, embedded systems, educational projects, and permanent prototype assembly.
