ESP-Mosaico

ESP-Mosaico: Modular development board driven by ESP32-S31 designed for coding agents and hardware creation.

ESP-Mosaico is a modular development board powered by the ESP32-S31 chip, built specifically for coding agents and physical computing. It combines an on-device agent runtime with an open desktop workspace to support chat coding and vibe coding on actual hardware. The board features a dual-core RISC-V processor running up to 320 MHz, Wi-Fi 6, Bluetooth 5.4, Thread 1.4, Zigbee 3.0, a 480 by 480 touch display, and high-speed USB 2.0. Users can expand its capabilities using plug-in modules such as an 8x8 RGB LED matrix, joysticks, cameras, and audio sensors. It serves makers and developers who want to build, deploy, test, and iterate AI-powered hardware applications.
