Using this breadboard is easy. First, if you need a thinner breadboard, just pull off the power rails on both sides. To make a larger breadboard, snap multiple breadboards together in the way you need. When you're ready to use it, remove the protective paper on the back and stick it to a flat and clean surface. This will keep the breadboard stable during your projects. As for maintenance, keep it away from water and dust. If it gets dirty, you can use a dry cloth to gently wipe it. Also, be careful when inserting components into the tie - points to avoid damaging them.
