24 PCS Prototype Board 4 Sizes Double Side Prototyping Board PCB Universal Printed Circuit Board Proto Board for Arduino
Quality PCB prototype board: high quality glass fiber, Sturdy material. Well etched and well drilled. The holes are centered well and all pads are nicely tinned, when you stack the boards up you can see clear through. Tinned plated finish prevents oxidation, not easy to deform
Quantity& sizes: 6 pieces 4X6 cm prototype PCB universal board; 6 pieces 2X8 cm prototype PCB universal board; 6 pieces 5X7 cm prototype PCB universal board; 6 pieces 3X7 cm prototype PCB universal board; total 24pcs PCB boards
Double-Side prototype PCB board are printed with letter-indicators representing each column of holes on one edge, marked for convenience for you to use, both sides are workable (solder pads, tinned holes)
Easy to solder: All the circuit boards are double sided and thick. Pre-tinned plated holes on the board make it very handy to solder components and sensors for your projects. also easy to cut with a rotary tool. suitable for less than expert soldering skills
