2.54 mm Pitch Electronic Circuit Prototype Board

This is an electronics prototyping circuit board. The pitch between holes is 2.54 mm, which is the pitch needed for DIP packaged devices. The electronic components can be added to one side, then soldered to the other. The holes are 1.5mm in diameter. The board thickness is 1.75 mm.

A 15x15 and a 30x30 hole prototyping circuit board are provided.

The circuit shown uses a 555 8-pin DIP timer chip.
