Add a micro-slice standard solderless breadboard to your Perma-Proto or other perf-board. This 2×4 point solder-less breadboard is a good way to add some solderless prototyping space if you just need to have a couple points. In our example photo, we put a chip and some jumper wires in the breadboard, but you can use anything with 0.1\” spaced header. Comes with one 18mm x 8mm x 8mm piece of solder-less breadboard. There are two white posts on the bottom for PCB positioning. In our example we snapped those off and soldered two of them into our Perma-Proto. Technical Details 2 rows of 4 holes Breadboard: 18mm x 8mm x 8mm / 0.7\” x 0.3\” x 0.3\” Metal pins: 3mm Weight: 1.4g
