When the circuit has been debugged long ago on a breadboard and it works great, wouldn't it be easy to turn it into a finished device without the hard work of manufacturing a printed circuit board?
This Breadboard PCB is a familiar full-size breadboard, but made specifically for soldering. All you have to do is transfer your components and solder them. You can finally take advantage of all the hard work you put into the design and skip the arduous task of recreating it for a PCB.
There are 830 contacts on this board. There are four rails on the sides designed for power and ground. Between the two of them there are 126 groups of interconnected contacts.
