Prototype Screw/Terminal Block Shield Board Kit For Arduino MEGA-2560 R3..
FR-4 fiber glass PCB, dual copper layers, size 120mm x 78mm..
Pads grid / pitch 2.54mm / 0.1", hole diameter 0.8mm. Terminal block pitch 3.5mm / 0.138", hole diameter 1.2mm..
Pitch 3.5mm / 0.138" mini terminal blocks, total 84 pins(3pole x24pcs, 2pole x6pcs )..

These PCB boards are great for assembly of a point to point style electronics board. Suitable for countless small electronics projects such as building a robot. If you are working with hobby electronics and want a more permanent circuit solution but don't want to design your own PCB, these are great for you!.
The prototyping boards we provide here are in the size of: Dimension: 80mm x 120mm / 3.15 x 4.72 inch (W*L).
They are made of FR-4 glass fiber, double sided with tinned through holes. This is a fast easy way to build small projects, the boards are durable and the tinned holes can take heat without lifting off..
Easy to cut with a rotary tool. The pre-drilled holes in each corner are great for building with two layers..
Please read the measurements before ordering if you are concerned about the size..
