The latest Adafruit ESP32-S3 Feather – now equipped with a dual-core processor and native USB capabilities. This upgraded version boasts 4 MB of flash memory and 2 MB of PSRAM. The native USB functionality allows it to function as a keyboard or a disk drive, eliminating the need for an external USB-to-Serial converter. With both WiFi and BLE capabilities, it’s a perfect fit for innovative IoT projects. Its compatibility with Feather Wings ensures expandability and access to a thriving community.
The ESP32-S3 stands out as a highly-integrated, energy-efficient 2.4 GHz Wi-Fi/BLE System-on-Chip (SoC) solution. It incorporates built-in native USB support along with novel features like Time of Flight distance measurements and AI acceleration. This SoC, renowned for its advanced power efficiency and RF performance, presents an ideal option for diverse applications in the realm of IoT, wearable technology, and smart homes.
Equipped with a powerful dual-core 240 MHz chip, the Feather ESP32-S3 offers performance comparable to the ESP32’s dual-core setup. Notably, it exclusively supports Bluetooth LE, omitting Bluetooth Classic support. This chip represents a significant advancement from its predecessor, the ESP32-S2. The mini-module used in the Feather variant includes 4 MB of flash memory, 2 MB of PSRAM, and ample 512 KB of SRAM. This configuration makes it perfect for applications demanding swift memory access, with SRAM offering speed and PSRAM providing a roomier option. Whether for CircuitPython support, extensive buffer needs, ESP-IDF utilization, or Arduino compatibility, this module excels in versatility and performance.
Features

ESP32-S3 Dual Core 240MHz Tensilica processor- the next generation of ESP32-Sx, with native USB so it can act like a keyboard/mouse, MIDI device, disk drive, etc!

Mini modulehas FCC/CE certification and comes with 4MByte of Flash, 2 MByte PSRAM

Power options- USB type CorLipoly battery

Built-in battery chargingwhen powered over USB-C

LiPoly battery monitor- MAX17048 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 QTconnector for I2C devices, with switchable power, so you can go into low power mode.

On/Charge/UserLEDs + statusNeoPixelwith 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. Quiescent current is from the power regulator, ESP32-S3 chip, and Lipoly monitor. Turn off the NeoPixel and external I2C power for the lowest quiescent current draw.

Works with ESP-IDF, Arduinoor CircuitPython
