Adafruit ESP32-S3 Feather 8MB with w.FL Antenna

The Adafruit ESP32-S3 Feather with w.FL Antenna features the dual-core ESP32-S3 with Wi-Fi, Bluetooth LE, and native USB in the Feather form factor, plus a w.FL (MHF3/IPEX3) connector for attaching an external 2.4 GHz antenna. This makes it ideal for enclosed installations or when you need improved range from a larger dipole.

This version comes with 8 MB flash and 512 KB SRAM (no PSRAM). The dual-core 240 MHz processor with native USB means it can act as a keyboard, mouse, MIDI device, or disk drive. It includes USB-C, LiPo battery charging and monitoring, a STEMMA QT port with switchable power, and a NeoPixel.
