This version comes with 8 MB flash, 512 KB SRAM, and no PSRAM — suitable for ESP-IDF, Arduino, and lighter CircuitPython projects that don't require large memory buffers.\n\nNative USB means it can act as a keyboard, mouse, MIDI device, or disk drive without an external USB-to-serial converter. It includes USB-C, LiPo battery charging and monitoring, a STEMMA QT port with switchable power, and a NeoPixel — all drawing approximately 100 µA in deep sleep.\n\nKey Features\n\n\nESP32-S3 Dual-Core 240 MHz Tensilica – Wi-Fi and Bluetooth LE (no Bluetooth Classic)\n\nNative USB – HID, MIDI, mass storage, and CDC serial without an external chip\n\n8 MB Flash + 512 KB SRAM – Large flash storage (no PSRAM)\n\nUSB-C – Power, charging, and native USB communication\n\nLiPo Battery Support – JST connector with charging and battery fuel gauge monitoring\n\nSTEMMA QT / Qwiic – I2C port with independently switchable power\n\nNeoPixel – Addressable RGB LED with controllable power pin\n\nLow Power – ~100 µA deep sleep current\n\nFCC/CE Certified Module – Compact module with PCB antenna\n\nFeather Form Factor – Compatible with FeatherWings\n\n\nAlso Available\n\nESP32-S3 Feather with 4 MB Flash + 2 MB PSRAM\nESP32-S3 Feather 8 MB with w.FL Antenna\n\nESP32-S3 TFT Feather (with built-in colour display)\n\nESP32-S3 Reverse TFT Feather (display on back for panel mounting)\n\nESP32 Feather V2 (classic ESP32, Bluetooth Classic + LE)\n\n\nIdeal For\n\nWi-Fi and BLE IoT devices with native USB\nUSB HID and MIDI projects\nESP-IDF and Arduino development\nBattery-powered wireless sensor nodes\n\n\nPackage Contents\n\n1× Adafruit ESP32-S3 Feather with STEMMA QT\n\n\n\nNote: This version has no PSRAM.
