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

The Adafruit ESP32 Feather V2 is a major redesign of the original HUZZAH32 ESP32 Feather, featuring 8 MB flash, 2 MB PSRAM, USB-C, a STEMMA QT port, a NeoPixel, and a user button. The dual-core ESP32 at 240 MHz provides Wi-Fi and Bluetooth Classic/LE connectivity for wireless and IoT projects.

Designed for low power usage, the V2 draws approximately 70 µA in deep sleep and 1.2 mA in light sleep from a LiPo battery. The STEMMA QT port has its own switchable 3.3V regulator, allowing you to completely power down I2C peripherals for ultra-low-power operation. The NeoPixel also has a controllable power pin.
