This is a cute, half-size breadboard with 400 tie points, good for small projects. It's 3.25" x 2.2" / 8.3cm x 5.5cm with a standard double-strip in the middle and two power rails on both sides. You can pull the power rails off easily to make the breadboard as thin as 1.4" (3.5cm). You can also "snap" these breadboards together, either way, to make longer and/or wider breadboards. The back is made of foam double-sided tape, if you remove the protective paper you can attach it to a flat clean surface.

As of June 10, 2022 - This half-size breadboard has been updated to Premium, making plugging and unplugging boards and headers a buttery-smooth operation thanks to upgraded spring clips. Updated design also includes a metal plate.
