The VC-02-Kit is a development board designed for the VC-02 module, and it is shared the same board with VC-01-Kit. The development board integrates CH340C serial port to USB chip, providing basic debugging interface and USB upgrade interface, design of wake up light and cold and cooling lamp, provides status indication and control instructions, and easy to debug the simple control function. VC-02 is a low-cost pure offline speech recognition module developed by Shenzhen Ai-Thinker Technology Co., Ltd. The module uses the voice chip US516P6 launched by Unisound, and continuously optimizes and innovates algorithms in speech recognition technology. The offline recognition algorithm and chip architecture are deeply integrated to provide customers with ultra-low-cost offline speech recognition solutions. It can be widely and quickly applied to smart home, all kinds of smart small household appliances, 86 boxes, toys, lamps and other products that need voice control. The US516P6 chip uses a 32-bit RSIC architecture core and incorporates a DSP instruction set specifically for signal processing and speech recognition, an FPU arithmetic unit that supports floating-point operations, and an FFT accelerator. VC-02 supports offline identification of 150 local instructions, RTOS lightweight system, rich peripheral interfaces, and simple and friendly custom tools.
