These half-sized perma-proto boards from Adafruit function similarly to standard perf-boards in that through-hole parts must be soldered to the board, but the holes are internally connected like on a 420-point breadboard, with four bus lines that each span the length of the board and 30 rows of electrically connected pins. They also feature a labeled silkscreen and mounting holes, which make it easy to transfer your prototype to a permanent circuit board and project box. These boards are sold in packs of three.

These Adafruit Perma-Proto Half-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 30 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 two 14-pin DIP ICs 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 3.2″ × 2.0″, is 0.063″ thick, and has two 0.125″ mounting holes for #4 or M3 screws spaced 1.9″ apart. These boards use 47 mil (1.2 mm) 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.

In addition to a variety of sizes of rigid perma-proto boards – quarter, half, and full – we also carry a flexible perma-proto board from Adafruit.
