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”.
