Feature●High quality: These double-sided PCB circuit boards are made of high-quality FR4 glass fiber, and the thickness is double-sided. General-purpose prototype PCB boards for point-to-point soldering are tinned●Board size: The general board is 4 x 6 cm, 2. 54 mm hole spacing, and the hole diameter is approximately. The 4 mounting holes at the four corners of the 1mm board are very convenient to install●Durable: The double-sided PCB circuit board is sturdy and easy to use, and the plating holes are pre-tinned and very strong. The reference numbers are printed on both sides for easy reference to each hole, which is very suitable for building electronic circuit prototypes●Purpose: The board is treated with flux, which is convenient for welding and prolongs its service life. PCB boards are ideal for transferring circuits from breadboards to printed circuit boards. Suitable for DIY, electronic design, etc.●The package includes: A total of 10 prototype circuit empty breadboards are included in the package, which is sufficient for various electronic and soldering projects. You can also cut these circuit boards into any shape you like when designing your own kits, electronic experiments and DIY projectsDescription Specification:
