The QT Py is a tiny microcontroller board from Adafruit. It packs an impressive amount of connection options into a small footprint. There is SPI, I2C, UART, I2S, eleven digital I/O, nine analogue inputs, one true analogue output, nine PWM outputs, six capacitive touch inputs, and one on-board NeoPixel.
Given the name, it should come as no surprise that there’s also an I2C connection in a STEMMA QT adapter, so you can plug any STEMMA QT or Qwiic devices straight in. In other words, this can communicate with almost anything.
The board gets a 9/10, “A huge potential in a small package”.
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.
