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

The Adafruit ESP32 Feather V2 with w.FL Antenna features the powerful ESP32 dual-core 240MHz processor with 8MB Flash and 2MB PSRAM. This updated version includes a w.FL antenna connector for attaching an external RF adapter or antenna, making it perfect for enclosures or for increased antenna gain with a larger dipole.

This board comes with a mini module that has FCC/CE certification, USB Type C port, built-in battery charging, and a separate controllable 3.3V power supply for STEMMA QT that allows ultra-low power consumption with attached sensors. It supports WiFi and Bluetooth® Classic/LE functionality, making it ideal for wireless or internet-connected projects.
