What has your favorite Espressif WiFi microcontroller, comes with our favorite connector – the STEMMA QT, a chainable I2C port, and has lots of Flash and RAM memory for your next IoT project? What will make your next IoT project flyyyyy? What a cutie pie! Or is it… a QT Py? This diminutive dev board comes with one of our new favorite lil chips, the ESP32-S2!

The ESP32-S2 is a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) solution that now has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.

Please note the QT Py ESP32-S2 has a single-core 240 MHz chip, so it won’t be as fast as ESP32’s with dual-core. Also, there is no Bluetooth support. However, we are super excited about the ESP32-S2’s native USB which unlocks a lot of capabilities for advanced interfacing! This ESP32-S2 mini-module we are using on the QT Py comes with 4 MB flash and 2 MB PSRAM so you can buffer massive JSON files for parsing!


  1. Same size, form factor, and pin-out as Seeed Xiao
  2. USB Type C connector – If you have only Micro B cables, this adapter will come in handy!
  3. ESP32-S2 240MHz Tensilica processor – the next generation of ESP32, now with native USB so it can act like a keyboard/mouse, MIDI device, disk drive, etc!
  4. 4 MB Flash & 2 MB PSRAM
  5. Native USB supported by every OS – can be used in Arduino or CircuitPython as USB serial console, MIDI, Keyboard/Mouse HID, and even a little disk drive for storing Python scripts.
  6. Can be used with Arduino IDE or CircuitPython
  7. Built-in RGB NeoPixel LED with power control to reduce quiescent power in deep sleep
  8. Battery input pads on the underside with diode protection for external battery packs up to 6V input
  9. 13 GPIO pins:
    11 on breakout pads, 2 more on QT connector
    10 x 12-bit analog inputs (SPI high-speed pads do not have analog inputs)
    8-bit analog output DAC
    PWM outputs on any pin
    Two I2C ports, one on the breakout pads, and another with STEMMA QT plug-n-play connector
    Hardware UART
    Hardware SPI on the high-speed SPI peripheral pins
    Hardware I2S on any pins
    5 x Capacitive Touch with no additional components required
  10. 3.3V regulator with 600mA peak output
  11. Light sleep at 2~4mA, deep sleep at ~70uA
  12. Reset the switch for starting your project code over, and boot the 0 buttons for entering bootloader mode
  13. Really really small
