HackSpace Magazine Issue 52: Adafruit QT Py ESP32-S2 #ESP32 #QTPy @HackSpaceMag

HackSpace Magazine — Issue 52 looks in-depth at the Adafruit QT Py ESP32-S2 microcontroller board.

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.”
