We got a request from a customer for a board that makes connecting between a breadboard and Stemma QT or Qwiic components easy, and here’s what we whipped up!
The Adafruit Qwiic / Stemma QT Breakout Board is pretty simple: on one end is a JST SH-compatible connector, that will let you plug-and-play to the Qwiic or Stemma QT universe. On the other side is four 0.1″ spaced pads where you can solder header or wires as you wish. In between are two 10K pullup resistors from the two I2C SDA/SCL lines to the positive power pin, plus a green ON LED so you know when the power pin and ground are properly wired.
And that’s it! Simple but effective. You can use it both with ‘I2C controllers’ like a Feather, Metro, QT Py, or with ‘I2C devices’ like sensors, OLEDs or GPIO expanders. Since the lines just pass through, you can use it with 3 or 5V power and logic. The LED and pull-up resistors can be deactivated by cutting some small traces on the back of the PCB, if they are not needed.

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.
