Adafruit
Half-Size Breadboard
Best solderless prototyping solution for hobbyists and electronics students.
This half-size breadboard from Adafruit is perfect for your smaller electronics projects. Measuring 2.2" x 3.4", it offers a standard double-strip in the center and dual power rails on the sides. You can easily remove the power rails to achieve a slimmer profile, making it ideal for fitting onto Arduino proto-shields. For greater flexibility, this breadboard can be cut in half to create two mini boards or snapped together with others to build larger custom configurations. It also comes with an adhesive backing for convenient mounting, providing a solderless prototyping solution.

What customers say
Customers highly value this breadboard for its exceptional reliability and superior quality, making it a prototyping staple. A key highlight is the firm seating of components, ensuring excellent electrical contact that avoids the frustrating intermittent issues common with lesser boards. The clear labeling significantly aids assembly and debugging for all skill levels. Its half size offers great versatility for compact yet moderately complex circuits. While priced slightly higher, users agree the premium is justified by the enhanced dependability and reduced development frustration. This product delivers flawless core functionality, proving a worthwhile investment for serious electronics work.
Know before you buy
Yes, these breadboards are designed to be stackable. You can snap multiple units together side-by-side to expand your prototyping area as your project grows.
Yes, the dual power rails on the sides can be easily detached. This allows you to achieve a slimmer profile, which is particularly useful when mounting the board onto Arduino proto-shields.
It features a peel-and-stick adhesive backing, allowing you to mount the board directly onto a flat surface or inside a project case for a permanent, stable setup.
Yes, the board is designed to be cut in half if you need two smaller, independent mini-boards for separate, smaller circuits.
This board uses the industry-standard 0.1" (2.54mm) pitch, making it fully compatible with standard jumper wires, DIP-packaged integrated circuits, and most common electronic components.
