32 pieces double-sided prototype boards of 6 different size to meet your demands, for electronic experiments and DIY projects.

Pre-tinned plated holes on the board make it very handy to solder components and sensors for your projects.

4 mounting holes at the corners of the board are very convenient for installing them together.

Work with sodering welding led diode, screw terminal, dupont wire, connector, resistor, IC, DIP, sensors, transistor and other eletronic power components or devices with .1" pin spacing. For Hobby Test, Computer Science Class experiments, point-to-point DIY IoT projects,Raspberry rasp Pi connection Perf Board.

Lettering on both side of the PC board makes it easier for prototyping projects, Cuttable fiber glass and FR-4 flame resistant good for soldering,Muti Pins, easy to cut and solder with appropriate tools. Flux for easy soldering and extended serving life of printed blank plating thru perforated board.
