ESP32-S31

RISC-V microcontroller with Wi-Fi 6 and edge AI acceleration

About ESP32-S31

ESP32-S31 is a wireless system on a chip for building connected devices with local AI, audio, and display capabilities. Its dual-core RISC-V processor runs at up to 320 MHz, with SIMD acceleration for signal processing and neural-network workloads. Integrated Wi-Fi 6, Bluetooth 5.4, and IEEE 802.15.4 support a range of wireless connections, while a Gigabit Ethernet MAC enables wired networking.

Developers can start with a compatible module or development board, connect cameras, displays, sensors, or audio peripherals, and build firmware using ESP-IDF. The official developer platform brings together hardware documentation, software guides, examples, and community projects. The chip is available for purchase and suits prototypes such as smart speakers, home hubs, and interactive control panels; individual software features depend on the framework and version used.
