These Adafruit Perma-Proto Full-Sized Breadboard PCBs bridge the gap between solderless breadboards and standard perf-boards by providing a through-hole layout similar to a breadboard that allows for permanent solder connections. Each board contains four bus lines that can be used for two independent power supplies and 60 rows of through-holes that are divided into two blocks, just like on a typical breadboard. The five-pin rows of each block are electrically connected, minimizing the need to use extra wires to make connections. This configuration makes it possible to mount up to four 14-pin DIP IC and easily connect other components to their pins. The electrical connections of all the through-holes on the perma-proto board can be easily viewed from the back side.

These boards are sold in packs of three. Each board measures 6.2³—2.0³, is 0.063³ thick, and has three 0.125³ mounting holes for #4 or M3 screws spaced 2.95³ apart. These boards use 47mil (1.2mm) diameter through holes to accommodate parts with thick leads like diodes. In addition, all of the holes on the board are through-plated for strength and feature a gold-plate finish to prevent oxidation. There is also no solder mask, so you can easily cut traces.

If you want to make temporary connections to these protoboards, you can solder in 0.1³ terminal blocks, which work well with stripped, unterminated wires, or male or female headers, which work with our premium jumper wires and wires with pre-crimped terminals. The picture below shows a quarter-sized Perma-Proto board with some 0.1³ terminal blocks and a 0.1³ male header:
