Applications
Key Specifications
Getting Started
Developers can use the Espressif IoT Development Framework (ESP-IDF) or the Arduino IDE for firmware development. To begin hardware evaluation, the ESP32-S3-DevKitC-1 series provides a compatible breadboard-friendly platform. Note that an external 2.4GHz antenna with a U.FL connector is required for operation, as there is no on-board PCB antenna.
Dev Boards
Development boards and breakout modules featuring the ESP32-S3-WROOM-1U-N8R2 or compatible chips — ready to use for prototyping.
