YunDo Hardware Versions

YunDo V1

YunDo V1 is open-source smart hardware product designed to simplify the development of voice interaction and smart devices. Its hardware specifications are as follows:

• Core Processor: ESP32
• Flash: 512kB
• Memory: 4MB
• Integrated Digital Microphone: ICS43434
• Integrated Digital Amplifier: MAX98357
• Communication Interface: I2S
• Power Management: Supports lithium battery power but lacks power management functionality

For more details and source code, please refer to YunDo V1 GitHub Repository.

YunDo V2

YunDo V2 is our latest smart hardware product, offering enhanced performance and additional features compared to the V1 version. Its hardware specifications are as follows:

• Core Processor: ESP32-S3
• Flash: 16MB
• Memory: 8MB
• Integrated Digital Microphone: ICS43434
• Integrated Digital Amplifier: MAX98357
• Communication Interface: I2S
• Power Management: Supports lithium battery power with integrated power management functionality

YunDo V2 also includes the following hardware improvements:

• Pin Header: Added pin header interface to expose commonly used pins, simplifying connections with other devices
• Battery and Speaker Connectors: Replaced with 1.25 2p connectors to ensure a more secure and stable connection for the battery and speaker
• Recording Button: Relocated to the left side of the device to avoid obstructing the Wi-Fi antenna when held
• External Antenna: ESP32-S3 module uses an external antenna for more stable communication

YunDo V2 is developed based on ESP-ADF and supports the following features:

• Voice Wake-Up: Supports various wake words
• VAD Detection: Voice Activity Detection
• Continuous Dialogue: Supports extended conversation
• Multilingual Support: Supports TTS (Text-to-Speech) and STT (Speech-to-Text)
• Model Compatibility: Supports commercial models like ChatGPT and open-source models like LLaMA
• Server Integration: Integrates LiveKit and AI Agent, providing rich server-side functionalities

Additionally, YunDo V2 also supports MicroPython and can use the MicroPython firmware from YunDo V1. However, we recommend using the ESP-ADF-based version to fully leverage advanced features like voice wake-up and continuous recognition, offering greater efficiency.
