- Onboard Audio Hardware: Integrated microphone and speaker output connector let you prototype voice interactions immediately out of the box.
- Simple UART Communication: Sends recognized command IDs over serial, making it easy to interface with Arduino, ESP32, STM32, Raspberry Pi, or any microcontroller.
- USB Type-C Connectivity: Modern USB-C port for power supply and firmware programming - no extra adapters needed.
- Breadboard-Friendly Design: Pin headers allow quick prototyping on standard breadboards without soldering.
- Low Power Consumption: Efficient AI SoC designed for always-listening applications in battery-powered or embedded products.
- Compact & Embeddable: Small form factor makes it easy to integrate into final product enclosures and custom PCBs.
Why Choose the Ai-Thinker VC-02-Kit?
- 100% authentic Ai-Thinker product sourced from authorized distribution channels
- Complete development kit - start building voice-controlled projects within minutes
