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 used on the QT Py comes with 4 MB flash and 2 MB PSRAM so you can buffer massive JSON files for parsing!

OLEDs! Inertial Measurement Units! Sensors a-plenty. All plug-and-play thanks to the innovative chainable design: SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! Just plug in a compatible cable and attach it to your MCU of choice, and you’re ready to load up some software and measure some light.

Pinout and shape are Seeed Xiao compatible, with castellated pads so you can solder it flat to a PCB. In addition to the QT connector, Adafruit also added an RGB NeoPixel (with controllable power pin to allow for ultra-low-power usage), a reset button (great for restarting your program or entering the bootloader) and a button on GPIO 0 for entering the ROM bootloader or for user input

Runs Arduino like a dream, and CircuitPython projects are fantastically fun.

Same size, form-factor, and pin-out as Seeed Xiao
USB Type C connector
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 MB Flash & 2 MB PSRAM
Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, MIDI, Keyboard/Mouse HID, even a little disk drive for storing Python scripts.
Can be used with Arduino IDE or CircuitPython
Built-in RGB NeoPixel LED with power control to reduce quiescent power in deep sleep
Battery input pads on underside with diode protection for external battery packs up to 6V input
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 puns
Hardware I2S on any pins
5 x Capacitive Touch with no additional components required

3.3V regulator with 600mA peak output
Deep sleep at 100uA
Reset switch for starting your project code over, boot 0 button for entering bootloader mode
Really really small

Technical Details

Revision History:

Before Feb 28, 2022 - Please note there is a hardware bug in the current revision of the PCB that causes deep sleep to draw ~6mA,
As of Monday, February 28th, 2022, the onboard antenna has been rotated to give a better response. Adafruit have also fixed low power sleep mode, so deep sleep can get down to 70uA

Product Dimensions: 21.8mm x 17.9mm x 5.7mm / 0.9" x 0.7" x 0.2"
