{"title":"Adafruit ESP32 Feather V2 -  8MB Flash + 2 MB PSRAM","handle":"adafruit-esp32-feather-v2-8mb-flash-2-mb-psram","url":"/products/adafruit-esp32-feather-v2-8mb-flash-2-mb-psram","description":"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.\n\nDesigned 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.\n\nKey Features\n\n\nESP32 Dual-Core 240 MHz Xtensa – Wi-Fi and Bluetooth Classic/LE\n\n8 MB Flash + 2 MB PSRAM – Significantly more storage and memory than the original\n\nUSB-C – Modern connector for power, charging, and serial communication\n\nCP2102N USB-Serial – Up to 3 Mbps for fast firmware uploads with auto-reset\n\nLiPo Battery Support – JST connector with built-in charging and voltage monitoring\n\nUltra-Low Power – ~70 µA deep sleep, ~1.2 mA light sleep\n\nSTEMMA QT / Qwiic – I2C port with independently switchable 3.3V power\n\nNeoPixel – Addressable RGB LED with controllable power pin\n\nUser Button – Tactile switch on pin 38\n\nFCC/CE Certified Module – Compact Pico module with PCB antenna\n\nFeather Form Factor – Compatible with 50+ FeatherWings\n\n\nAlso Available\n\nESP32 Feather V2 with Pre-Soldered Headers\nESP32 Feather V2 with w.FL Antenna Connector\nESP32-S3 Feather\n\nESP32-C6 Feather (Wi-Fi 6 + Zigbee/Thread)\n\n\nIdeal For\n\nWi-Fi and Bluetooth IoT projects\nBattery-powered sensor nodes requiring ultra-low sleep current\nProjects needing large data buffers (2 MB PSRAM)\nArduino and MicroPython development\n\n\nPackage Contents\n\n1× Adafruit ESP32 Feather V2 (fully assembled)\n1× Header strip (unsoldered)\n\n\n\nNote: Some pin numbers for I2C, UART, and SPI have changed from the original HUZZAH32. Use the board definition's symbolic names (SDA, SCL, etc.) rather than hardcoded pin numbers. LiPo battery and USB cable sold separately.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2462,"title":"Default Title","sku":"AF-5400","price":42.06,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":103,"option1":"Default Title"}]}
