Adafruit offers a high-quality alternative to perforated grid boards with the Perma Proto boards. The Perma Proto board combines the advantages of a breadboard with those of a breadboard. Project development can be done directly on the board instead of on a breadboard. When the project is mature, the components used can be soldered. The Perma Proto boards are the PCB you have always wanted to prototype. The basic layout corresponds to that of a middle breadboard. The top of the board is covered with a white lacquer and features the same markings and labels as a breadboard. The holes have been created with a 1.2 mm drill, so that cables with a larger diameter can also be connected. All holes are contact-plated. The use of gold plating does not cause oxidation like conventional copper. Each board has two mounting holes. This kit contains 3 Adafruit Perma Proto boards.
