Product Descriptions
VC-02-Kit is an offline voice development board designed for the VC-02 module, which is shared with VC-01-Kit.
The VC-02-Kit development board integrates the CH340C serial port to USB chip, providing basic debugging and USB upgrade interfaces; The design of wake-up lights and heating/cooling lights provides status indication and control indication, and is easy to debug with simple control functions.
Supports offline recognition of 150 local instructions, supports lightweight RTOS systems, has rich peripheral interfaces, and simple and user-friendly customization tools. Built in 242KB high-speed SRAM and 2MB FLASH; Supports 5V power input, with built-in 5V to 3.3V and 3.3V to 1.2V LDO for chip power supply.
We continuously optimize and innovate algorithms in speech recognition technology, deeply integrating offline recognition algorithms with chip architecture to provide customers with ultra-low cost offline speech recognition solutions. These solutions can be widely and quickly applied to smart homes, various smart small appliances, 86 boxes, toys, lighting fixtures, and other products that require voice control.
