The QT Py series of boards from Adafruit bring popular processors into a very small form factor (it’s compatible with Seeed Studio’s XIAO). This time, it’s the turn of the ESP32-S2 to get the QT Py treatment. Despite its teeny size, there are eleven GPIOs (plus an additional two on the STEMMA QT connector). Ten of these are 12-bit analogue inputs, and one is an 8-bit analogue output. There’s hardware I2C, SPI, and UART, and capacitive touch. All in all, there’s a lot of connectivity for such a small device, and we haven’t even got to WiFi yet.
They give Adafruit’s QT Py ESP32-S2 a perfect 10/10, saying “All the power and ease of use we’ve come to expect in ESP32-S2 boards made tiny and cheap.”

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.
