Product Description

VC01 / VC02 AI Intelligent Offline Voice Recognition Development Board

Network-Free Voice Control for Smart Home and IoT Projects

The VC01 and VC02 are highperformance, pure offline voice recognition development boards from AiThinker, powered by the US516P6 chip and designed for intelligent voice control without internet dependency [citation:1][citation:4][citation:12].

Offline Voice Recognition - 150 local command support with 98% recognition accuracy [citation:7][citation:12]
32bit RISC Core at 240MHz Built-in DSP, FPU, and FFT accelerator for fast processing [citation:5][citation:12]
Supply voltage: 5V (>500mA) via Micro-USB [citation:3][citation:9]
Default wake word: "你好，小安" with built-in Chinese/English models [citation:11]
Use the onboard CH340C USBtoserial for debugging and firmware upgrades [citation:4][citation:9]

Usage Tips

The VC01 and VC02 kits use the same development board with different module footprints [citation:8]. For quick testing, the board comes preloaded with a demo firmware with "小安小安" wake word [citation:11]. Customize voice commands using the opensource SDK [citation:1][citation:2].

Use the on-board reset button to enter programming mode after connecting USB [citation:11]
Keep the microphone 30-50cm away for best recognition performance [citation:1]
Firmware version must match board model [citation:1][citation:11]
