When the circuit has been debugged long ago on a half sized 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 half-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.
Unlike a full-size version, there are 400 pin holes on this board. It may be useful if the size of the device matters, and a full-size breadboard too large. There are four rails on the sides designed for power and ground.
