ESP32-S3

The ESP32-S3 is a dual-core Xtensa LX7 Wi-Fi/Bluetooth LE SoC, purpose-built for AIoT: featuring vector instructions for AI acceleration and robust hardware security.

This is a serious upgrade: the ESP32-S3 integrates a dual-core Xtensa LX7 processor clocked up to 240 MHz, paired with 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) radio. Crucially, it includes vector instructions for hardware-accelerated AI and neural network computing, targeting demanding AIoT applications like voice and image recognition. You get 512 KB of SRAM, support for high-speed Octal SPI flash/PSRAM (up to 16 MB), and a rich peripheral set, including USB OTG and up to 45 programmable GPIOs. Security is locked down with AES-XTS flash encryption, Secure Boot, and the 'World Controller' for isolated execution environments.
