Adafruit ESP32 Feather V2 - 8MB Flash + 2 MB PSRAM - STEMMA QT

The Adafruit ESP32 Feather V2 is a refreshed, redesigned version of the popular ESP32 Feather, now with significant upgrades to enhance performance and features. Built around the powerful ESP32 dual-core processor, this compact development board is perfect for WiFi and Bluetooth projects, offering excellent performance and flexibility.

Key Features:

• Dual-Core ESP32 Processor: Runs at 240MHz, offering both WiFi and Bluetooth Classic/LE support, making it ideal for wireless and Internet-connected applications.
• 8 MB Flash & 2 MB PSRAM: This upgrade allows for larger data buffers and improved performance, compared to the previous model with 4 MB Flash and no PSRAM.
• USB Type-C Port: Faster and more reliable than the previous Micro B port, offering better power and data transfer capabilities.
• Additional User Button: A new tactile switch on input pin 38 for added control.
• NeoPixel LED: Includes a mini RGB NeoPixel with a controllable power pin for visual feedback with minimal power consumption.
• STEMMA QT Port: For easy plug-and-play I2C connections with compatible devices, featuring switchable power for ultra-low power consumption.
• Low Power Operation: The board is optimized for low power usage, drawing as little as 70uA in deep sleep mode and 1.2mA in light sleep, making it perfect for battery-powered projects.
• Built-in Battery Charging: Supports LiPoly battery charging over USB-C, and includes a battery monitor with a 200K resistor divider.
• Upgraded USB-to-Serial Converter: The CH9102F chip replaces the older CP2102, enabling faster firmware uploads and stable serial communication.
• Smaller ESP32 Pico Module: The new module is more compact, enabling clearer breakout pad markings and additional mounting holes.

This ESP32 Feather V2 continues to be part of the Feather ecosystem, allowing you to expand your project with 50+ compatible FeatherWings for added functionality. It also supports Arduino and MicroPython environments, making it easy to program and customize for your needs.

Additional Features:

• Power Options: Choose between USB Type-C or LiPoly battery power.
• Charge/User LEDs: Includes charge and status LEDs along with a NeoPixel for visual feedback.
• Low Power Draw: Deep sleep current as low as 80~100uA with minimal quiescent current draw, allowing for long battery life.
• Full Assembly: Comes fully assembled and tested, ready for use with your projects. Includes a USB interface for easy programming with Arduino IDE or ESP32 IDF.

This board is a great choice for makers, engineers, and hobbyists looking for a reliable, low-power, wireless development platform with ample room for growth and expansion.
