The AdafruitQT Py ESP32-S2 is a compact Wi-Fi development board for IoT, wearable electronics and smart home projects. It uses the low-power ESP32-S2 system-on-chip, which provides 2.4GHz Wi-Fi, native USB and support for features such as Time of Flight distance measurement.
The single-core processor runs at 240MHz and is supported by 4MB of Flash and 2MB of PSRAM, providing enough memory to buffer and parse large JSON files. Please note that the ESP32-S2 is not as fast as dual-core ESP32 boards and does not support Bluetooth®.
A chainable STEMMA QT I2C connector allows compatible OLED displays, sensors and inertial measurement units to be connected without soldering. It also works with SparkFun Qwiic devices, while Seeed Grove I2C boards can be connected using a suitable adapter cable.
The pinout and board shape are compatible with the Seeed XIAO, and castellated pads allow the board to be soldered directly onto a PCB. Other onboard features include an RGB NeoPixel with a controllable power pin, a reset button and a GPIO 0 button for entering the ROM bootloader or use as a general input.
Please note: This board does not have an onboard antenna. A compatible uFL antenna, such as the 2.4GHz Mini Flexible Wi-Fi Antenna, or a uFL to RP-SMA adapter and suitable RP-SMA antenna is required. The antenna is not included. Do not use a uFL to SMA adapter.
Runs Arduino like a dream and CircuitPython projects are fantastically fun.
Features
Same size, form-factor, and pin-out as Seeed Xiao
USB Type C connector - If you have only Micro B cables, this adapter will come in handy!
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

Specifications
Dimensions: 21.8 x 17.9 x 5.7mm
Weight: 2.1g
Revision History
As of June 24, 2022 - This board may come with a different regulator than AP2112K due to parts shortages. The regulator can provide at least 500mA.
Before March 18, 2022 - Please note there is a hardware bug in the current revision of the PCB that causes deep sleep to draw ~6mA,
As of March 18th, 2022 - we've fixed low power sleep mode, so deep sleep can get down to 70uA
