Built around the dual-core ESP32 at 240 MHz with 8 MB flash and 2 MB PSRAM, it includes USB-C, LiPo battery charging and monitoring, a STEMMA QT port with switchable power, a NeoPixel, and a user button.\n\nDesigned for ultra-low power operation — approximately 70 µA in deep sleep and 1.2 mA in light sleep. The STEMMA QT port has its own switchable 3.3V regulator for powering down I2C peripherals independently, and the NeoPixel has a controllable power pin.\n\nKey Features\n\n\nPre-Soldered Headers – Ready to plug into a breadboard immediately\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\nCH9102F USB-Serial – Fast firmware uploads at up to 921600 bps 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\n\nESP32 Feather V2 (unsoldered 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\nQuick breadboard prototyping without soldering\nWi-Fi and Bluetooth IoT projects\nBattery-powered sensor nodes requiring ultra-low sleep current\nArduino and MicroPython development\n\n\nPackage Contents\n\n1× Adafruit ESP32 Feather V2 with pre-soldered headers (fully assembled)\n\n\n\nNote: Headers are pre-soldered and cannot be replaced with stacking headers. Some pin numbers for I2C, UART, and SPI have changed from the original HUZZAH32 — use 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":1130,"title":"Default Title","sku":"AF-5900","mpn":"ADA5900","price":35.43,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
