The Ai-Thinker NodeMCU-VC-02-KIT Offline Speech Recognition Module is a development board specifically designed for the VC-02 module.
 This development board incorporates a CH340C serial port to USB chip, which provides a basic debugging interface and a USB upgrade interface. It also features a wake-up light and a cooling lamp, which offer status indication and control instructions, thereby simplifying the debugging of control functions.
The VC-02 is a cost-effective, purely offline speech recognition module and utilizes the US516P6 voice chip, launched by Unisound, and consistently optimizes and innovates algorithms in speech recognition technology.
The offline recognition algorithm and chip architecture are deeply integrated to offer ultra-affordable offline speech recognition solutions.
This module can be extensively and rapidly applied to a variety of products that require voice control, including smart homes, various smart small household appliances, boxes, toys, lamps, and more.
