Adafruit Perma-Proto Half-sized Breadboard PCB – Single has the basic layout of a half sized breadboard, but it is a PCB. The top side of the breadboard PCB has a white silkscreen similar to a standard solderless breadboard and the bottom has the 5-hole pad design that matches the classic breadboard. Similar to standard breadboards, Adafruit Perma-Proto Half-sized Breadboard PCB – Single has 4 power lines. The drill holes have 1,2mm diameter, so there won’t be any problems while placing components with big leads and there are 2 mounting holes to attach the PCB to your project.
