Adafruit QT Py ESP32-S3 (No PSRAM)

The Adafruit QT Py ESP32-S3 packs Wi-Fi, BLE, a STEMMA QT connector, and 8 MB of flash into a board barely larger than a US quarter. USB-C powered, CircuitPython-ready, and small enough to live inside almost any project.

Pair with any STEMMA QT or Qwiic sensor for instant solder-free prototyping, or drop it into a wearable, a key-cap macro pad, or an embedded BLE bridge.
