Adafruit ESP32-S2 Feather - 4 MB Flash + 2 MB PSRAM - STEMMA QT / Qwiic

The Adafruit ESP32-S2 Feather is a versatile and powerful development board ideal for your next IoT project. Featuring an ESP32-S2 WiFi module, native USB support, and a STEMMA QT connector for easy integration with I2C devices, this board is packed with features for building connected projects.

Key Features:

• ESP32-S2 Chip: 240 MHz single-core processor from Espressif with native USB capabilities, enabling it to act as a keyboard, mouse, MIDI device, disk drive, and more.
• 4 MB Flash and 2 MB PSRAM: Generous memory for handling large data buffers, such as parsing massive JSON files.
• WiFi Connectivity: Ideal for IoT projects with built-in low-cost 2.4 GHz Wi-Fi support.
• Native USB: The ability to interface directly with USB devices opens up many possibilities for advanced applications.
• Power Options: Powered via USB Type-C or a LiPoly battery. It also supports built-in battery charging when powered over USB-C.
• Battery Monitoring: Includes a LiPoly battery monitor (LC709203) to track battery voltage and state of charge, with percentage reporting over I2C.
• Low Power Features: In deep sleep mode, the board can draw as little as 80~100uA from the LiPoly connection, making it highly efficient for battery-operated projects.
• STEMMA QT Connector: Simplifies connecting I2C devices with switchable power and supports low-power modes.
• Onboard LEDs: Includes on/charge/user LEDs and a NeoPixel with pin-controlled power for low power consumption.
• Buttons: Reset and DFU (BOOT0) buttons for easy access to the ROM bootloader via USB serial port.
• Compatibility: Works with both Arduino and CircuitPython, making it easy to get started with either platform.

Whether you're working on an IoT, wearable, or smart home project, the Adafruit ESP32-S2 Feather provides the power and flexibility you need to bring your ideas to life.
