Breadboard pcb pre-punched experiment boards 140X95MM
SPECS: 140x95mm, 29x50 holes (1450) 2.5mm edge pitch
This phenolic board that has a matrix of punched holes on a 0.1" (2.5mm) pitch with a `donut' of tin plated copper around each hole. Each donut is separated from its neighbours by about a 0.5mm gap. This effectively isolates each pad but also makes it easy to bridge solder across to make interconnections. Each board also has `fingers' on opposite ends. These can be used to connect to and from the board or to a card edge connector. Finally the non- solder side of the board has an alpha- numeric grid printed on it to assist in component identification board layout.
