Adafruit is celebrating Lunar New Year🐍 Wednesday 1/29/2025. In combination with MLKDay, shipping could be delayed. Please allow extra time for your order to ship!
This cute 3.2″ × 2.1″ (82 × 53mm) solderless half-size breadboard has four bus lines and 30 rows of pins, our favorite size of solderless breadboard for projects. You get a whoppin’ 400 tie points! Plug in a Feather or Metro Mini with the rest for sensors or buttons or even a little display.
You can pull the power rails off easily to make the breadboard as thin as 1.4″ (3.5cm). You can also cut these in half with a saw to create 2 tiny breadboards, or “snap” these breadboards together either way to make longer and/or wider breadboards.
The board also has an adhesive backing and 8 mounting holes for M2 or #2 screws on a 1 cm pitch. This makes it super easy to mount the breadboard to a chassis for your next robot friend! (Just be sure to grab some M2 standoffs and/or screws) Note that you’ll need an awl/screwdriver/tweezers to pop a hole thru the thin foam backing.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat and our Discord!
