ESP32-S3

Wi-Fi and Bluetooth microcontroller with AI acceleration

About ESP32-S3

ESP32-S3 is a wireless microcontroller for building connected devices that need local processing, sensing, and user interaction. Its dual-core Xtensa LX7 processor runs at up to 240 MHz and combines 2.4 GHz Wi-Fi with Bluetooth 5 Low Energy. Vector instructions accelerate neural-network and signal-processing workloads, helping developers add features such as voice recognition or image analysis to compact hardware.

The chip offers 45 programmable GPIOs, touch inputs, and interfaces for connecting sensors and other peripherals, along with support for external flash and PSRAM. Developers can prototype with compatible modules or development boards and build firmware using ESP-IDF. Secure boot, flash encryption, and low-power operating modes support the transition from experiments to deployed embedded products.
