Adafruit ESP32 Feather V2 w.FL Antenna - 8MB Flash + 2 MB PSRAM

The Adafruit ESP32 Feather V2 with w.FL Antenna is identical to the standard ESP32 Feather V2 but replaces the PCB trace antenna with a w.FL (MHF3/IPEX3) connector for attaching an external antenna. This makes it ideal for use inside enclosures or when you need improved range from a larger dipole antenna.

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. Designed for ultra-low power — approximately 70 µA in deep sleep.

Key Features

• w.FL Antenna Connector – MHF3/IPEX3 connector for external 2.4 GHz antenna (not a standard u.FL)
• ESP32 Dual-Core 240 MHz Xtensa – Wi-Fi and Bluetooth Classic/LE
• 8 MB Flash + 2 MB PSRAM – Significantly more storage and memory than the original
• USB-C – Modern connector for power, charging, and serial communication
• CP2102N USB-Serial – Up to 3 Mbps for fast firmware uploads with auto-reset
• LiPo Battery Support – JST connector with built-in charging and voltage monitoring
• Ultra-Low Power – ~70 µA deep sleep, ~1.2 mA light sleep
• STEMMA QT / Qwiic – I2C port with independently switchable 3.3V power
• NeoPixel – Addressable RGB LED with controllable power pin
• User Button – Tactile switch on pin 38
• Feather Form Factor – Compatible with 50+ FeatherWings
