Quick NK-850 Hot Air Rework Conversion Nozzle: If you’ve ever made a mistake when surface-mount soldering, you know how much of a pain it can be to fix it without the right tools. It can add critical time to a project and seriously dampen your soldering momentum if you run into a bad component or a faulty reflow. Boo hiss!
Adafruit ANO Rotary Navigation Encoder to I2C Stemma QT Adapter: The ANO rotary encoder wheel is a funky user interface element, reminiscent of the original clicking scroll wheel interface on the first iPods. It’s a nifty kit, but the pin-out is a little odd – and there’s a ton of pins needed to connect to the rotary encoder and 5 button switches.
This Stemma QT breakout makes all that frustration go away – solder in the ANO Directional Navigation and Scroll Wheel Rotary Encoder (not included). The onboard microcontroller is programmed with our seesaw firmware and will track all pulses and pins for you and then save the incremental value for querying at any time over I2C. Plug it in with a Stemma QT cable for instant rotary goodness, with any kind of microcontroller from an Arduino UNO up to a Raspberry Pi to one of our QT Py’s.

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.
