Adafruit QT Py ESP32-S2 WiFi Dev Board with STEMMA QT

The Adafruit QT Py ESP32-S2 is a compact and powerful development board featuring the ESP32-S2, a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) with built-in native USB. This board includes the STEMMA QT connector, making it easy to chain I2C sensors and devices without soldering.

Ideal for Internet of Things (IoT), wearable electronics, and smart home applications, the QT Py ESP32-S2 offers 4 MB flash memory and 2 MB PSRAM for handling complex projects with large buffers. It supports Arduino and CircuitPython programming environments.

• ESP32-S2 240 MHz single-core Tensilica processor with native USB support.
• 4 MB Flash and 2 MB PSRAM memory.
• USB Type C connector for modern connectivity.
• Built-in RGB NeoPixel LED with controllable power for low power usage.
• 13 GPIO pins with analog inputs, DAC output, PWM, capacitive touch support, hardware UART, SPI, and I2S peripherals.
• Two I2C buses, one with STEMMA QT plug-n-play connector.
• Battery input pads with diode protection for up to 6V input.
• Reset and bootloader buttons for easy programming and control.
• Compact size similar to Seeed Xiao with castellated pads for soldering to PCBs.

Use the QT Py ESP32-S2 to create versatile Wi-Fi enabled projects with easy sensor integration via STEMMA QT connectors, perfect for advanced interfacing including USB serial, MIDI, keyboard/mouse HID, and even mass storage for Python scripts.

Note: This board uses a single-core ESP32-S2, which is not as fast as dual-core ESP32 variants, and does not include Bluetooth support.
