The Digi-Key Innovation Handbook is your guide to keeping some of the most highly referenced content from Digi-Key at your fingertips while giving you plenty of room to keep your thoughts, projects, and ideas at hand. They highlight concepts, formulas, components, and electronic staples so you can refer to them at any time.
These NEMA-23 Size Stepper Motors come to us from X-Carve, they’re used by folks to make CNC machines so they’re very strong, fast and reliable. In the X-Carve, these run the three axes on their routing machine and have pulleys pre-attached (see datasheet for the pulley specification). For wiring, there’s a snap-in wiring harness
This cable is not only super-fashionable, with a woven pink and purple Blinka-like pattern, it’s also made for USB C for our modernized breakout boards, Feathers, and more. If you want something just like it but for Micro B, we have a B version here.
Add a cool touch interface with your project with this Panel Mount USB Trackpad with Three Buttons that is super easy to use and interface with. Simply plug it into your computer (desktop of single-board-linux type), it will appear as an external mouse with left and right buttons plus a middle button.
This magnificently Glowing Trackball has the positive qualities of a palantír: communicate with one another across vast distances, small, portable size, lovely dream-blue glow, and will certainly not trap you in a scary vision of a dystopic future. Even better, it comes with two mounting holes to install in your workspace.
This cable will make it super easy to use our plug-and-play STEMMA QT boards and controllers with chips, breakouts, and other devices that are I2C compatible but don’t come with a STEMMA QT socket already on ’em.
If you want to store calibration values, MAC addresses, non-secure access tokens, or other unique identifiers, EEPROM storage is a great option. EEPROM is long lasting, and doesn’t need to be written in pages – a single byte can be written at once (unlike with flash memory!) EEPROM storage persists even when the power goes out, and can be over-written literally one million times.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
