The new Adafruit ESP32-S3 Feather with dual core and native USB - this version comes with 4 MB flash, and 2 MB PSRAM compared to the Feather ESP32-S3 with 8MB Flash / no PSRAM version.

Native USB means it can act like a keyboard or a disk drive, and no external USB-to-Serial converter required. WiFi and BLE mean it's awesome for IoT projects. And Feather means it works with the large community of Feather Wings for expandability.

The ESP32-S3 is a highly-integrated, low-power, 2.4 GHz Wi-Fi/BLE System-on-Chip (SoC) solution that has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements and AI acceleration. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.

The Feather ESP32-S3 has a dual-core 240 MHz chip, so it is comparable to ESP32's dual-core. However, there is no Bluetooth Classic support, only Bluetooth LE. This chip is a great step up from the earlier ESP32-S2! This ESP32-S3 mini-module we are using on the Feather comes with 4 MB flash and 2 MB PSRAM, as well as lots of 512KB of SRAM so it's perfect for use with CircuitPython support or any time massive buffers are needed: for fast memory access use SRAM, for slower-but-roomier access use PSRAM. It's also great for use in ESP-IDF or with Arduino support.

Features:

ESP32-S3 Dual Core 240MHz Tensilica processor
Mini module has FCC/CE certification and comes with 4 MByte of Flash, 2 MByte PSRAM
Power options - USB type C or Lipoly battery
Built-in battery charging when powered over USB-C
LiPoly battery monitor - LC709203 chip actively monitors your battery for voltage and state of charge / percentage reporting over I2C
Reset and DFU (BOOT0) buttons to get into the ROM bootloader (which is a USB serial port so you don't need a separate cable!)
Serial debug output pin (optional, for checking the hardware serial debug console)
STEMMA QT connector for I2C devices.
On/Charge/User LEDs + status NeoPixel with pin-controlled power for low power usage
Low Power friendly! In deep sleep mode we can get down to ~100uA of current draw from the Lipoly connection.
Works with ESP-IDF, Arduino or CircuitPython
