## Description

The Adafruit QT Py ESP32-S3 packs dual-core 240 MHz processing, Wi-Fi, Bluetooth LE, and native USB into the tiny QT Py form factor. With 8 MB flash and 512 KB SRAM, it's a significant step up from the ESP32-S2 — adding a second core, BLE support, and more memory while keeping native USB for CircuitPython disk-drive mode, HID devices, and MIDI. Program it with CircuitPython, Arduino, or ESP-IDF. The STEMMA QT / Qwiic connector gives you plug-and-play I2C access to hundreds of sensors, and the Seeed Xiao-compatible pinout with castellated pads makes it easy to embed in custom designs. Key Features ESP32-S3 Dual-Core Tensilica – 240 MHz with 8 MB flash and 512 KB SRAM Wi-Fi 2.4 GHz – Built-in Wi-Fi for IoT connectivity Bluetooth LE – BLE support for wireless peripherals and mesh (no Bluetooth Classic) Native USB – USB keyboard/mouse HID, MIDI, serial console, and disk drive support USB-C Connector – For programming, power, and USB device functions STEMMA QT / Qwiic Connector – Plug-and-play I2C for sensors and accessories RGB NeoPixel LED – With controllable power pin for ultra-low-power sleep 13 GPIO Pins – 10× 12-bit ADC, PWM on any pin, 5× capacitive touch Two I2C Ports – One on breakout pads, one on STEMMA QT connector Hardware UART, SPI & I2S – Full peripheral support CircuitPython & Arduino – Full support for both platforms 3.3 V Regulator – AP2112 with 600 mA peak output Battery Input Pads – On the underside with diode protection for up to 6 V Low Power Modes – Light sleep at 2–4 mA, deep sleep at ~70 µA Seeed Xiao Compatible – Same size and pinout with castellated pads Also Consider QT Py ESP32-S3 with 2 MB PSRAM – Same chip with added PSRAM for larger buffers QT Py ESP32-S2 – Single-core with native USB (no BLE) QT Py ESP32 Pico – Classic ESP32 with Bluetooth Classic + BLE (no native USB) QT Py ESP32-C3 – RISC-V core with Wi-Fi + BLE (lower cost, no native USB) Ideal For Wi-Fi + BLE IoT projects with native USB CircuitPython development with wireless connectivity USB HID devices (keyboards, mice, MIDI controllers) Compact wireless sensors and controllers Battery-powered low-power wireless projects Note: This version has no PSRAM. If your project requires large buffers (e.g. image processing or large JSON parsing), consider the QT Py ESP32-S3 with 2 MB PSRAM. The ESP32-S3 supports Bluetooth LE only — not Bluetooth Classic.
