EchoEar is an intelligent AI development kit designed for creating advanced voice interaction and multimedia systems. The device is perfect for projects such as smart toys, smart speakers, central control systems, and other products requiring high computing performance.

EchoEar is built around the ESP32-S3-WROOM-1-N16R16VA module, which supports Wi-Fi 2.4 GHz and Bluetooth 5 (LE), ensuring efficient wireless communication. With integration capabilities for large-scale AI models such as OpenAI, Xiaozhi AI, and Gemini, it enables full-duplex voice interaction, speech recognition, and intelligent AI agent control. The device features a 1.85-inch round QSPI touch display with a resolution of 360×360 pixels, using the ESP32-S3’s native touch sensors to provide an intuitive and interactive experience. It includes a dual LMA3729T381-OY3S microphone array supporting local voice wake-up and sound source localization, allowing for natural communication with the device. The built-in 3 W speaker delivers clear and powerful audio, ideal for interactive voice applications.
EchoEar comes with 16 MB of Flash and 16 MB of PSRAM, along with a microSD card slot supporting up to 32 GB, enabling storage of large multimedia datasets. The power system supports both 5 V DC input and 3.7 V lithium battery, providing flexibility for portable applications. Through its USB-C interface, the device can be easily charged, programmed, and debugged. The design also includes a Pogopin connector for convenient expansion with additional modules. EchoEar integrates several advanced electronic components, such as BQ27220 (battery management), TP4057 (charging controller), TLV62569 (DC/DC converter), and SAM8108 (power control). A single press of the POWER button allows users to easily turn the device on or off, simplifying testing and operation during development.

The kit is designed for AI solution developers who require a compact, powerful, and feature-rich platform for creating edge AI applications. By combining high performance, offline voice recognition, and extensive integration flexibility, EchoEar provides a solid foundation for next-generation intelligent device projects.
