Chanzon 34 Pcs Double Sided PCB Board Tinned Through Holes (5 Sizes 2X8 3X7 4X6 5X7 7x9) Prototype Kit FR4 Printed Universal Circuit Perfboard for DIY Soldering Project Compatible with Arduino Kits

Key features

• These double side (DS) pcbs with plated through holes design, Each hole on the same side are electrically isolated (NOT a stripboard or sigle side) solderable, You can solder to bridging holes together or use 22-29awg jumper wires for connection. Isolate points bare Pre-tined perfboard.
• 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.
