Espressif ESP32-S3-BOX-3 AIoT Evaluation Kit

Description

The ESP32-S3-BOX-3 is Espressif’s premier audio-focused AIoT evaluation platform, built around the high-performance ESP32-S3 microcontroller. This kit provides a complete hardware foundation for developing voice-controlled smart devices, leveraging the chip’s vector instructions for AI acceleration to run Espressif’s ESP-SR speech recognition pipeline locally. The integrated 2.4-inch touchscreen offers a user interface for interactive applications, while the dual MEMS microphones enable robust far-field voice capture.

Engineered for low-power operation and scalable deployment, the board features a rich set of expansion ports including USB-C for power and programming, a PCIe connector for high-speed peripherals, and a Pmod interface for additional sensors. Its compact form factor houses 16MB of flash and 16MB of PSRAM, providing ample memory for complex audio processing algorithms and multilingual voice command sets without relying on cloud connectivity.
