It features an integrated CH340C USB-to-serial chip for debugging and upgrading, with added functionality like wake-up light, cold, and cooling lamp control, along with status indicators for easy debugging and control. Developed by Shenzhen Ai-Thinker Technology Co., Ltd., the VC-02 is a cost-effective offline speech recognition module that uses the US516P6 voice chip from Unisound. This chip offers a deep integration of offline recognition algorithms, providing an ultra-low-cost speech recognition solution. It is ideal for smart homes, small household appliances, 86 boxes, toys, lamps, and more, enabling voice control. The US516P6 chip features a 32-bit RISC architecture, DSP instructions for signal processing, an FPU unit for floating-point operations, and an FFT accelerator. The VC-02 Voice Recognition Module supports 150 local offline commands and a lightweight RTOS system, making it easy to customize with a variety of peripheral interfaces.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAll GPIOs can be set up as external interrupt inputs and wake-up sources\u003c\/li\u003e\n\u003cli\u003eOne full-duplex UART with a maximum speed of 3Mbps\u003c\/li\u003e\n\u003cli\u003eSupports I2C, DAC, PWM, and multiple interfaces\u003c\/li\u003e\n\u003cli\u003eIncludes 242KB of high-speed SRAM\u003c\/li\u003e\n\u003cli\u003eEquipped with 2MB FLASH memory\u003c\/li\u003e\n\u003cli\u003eDual-channel DAC output support\u003c\/li\u003e\n\u003cli\u003e32-bit RISC core running at 240MHz\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSupports DSP instruction set and FPU for floating-point operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eItem Type\u003c\/th\u003e\n\u003ctd\u003eAI and Voice Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eAi-Thinker VC-02-Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupply Voltage (V)\u003c\/th\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCurrent (mA)\u003c\/th\u003e\n\u003ctd\u003e500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight (g)\u003c\/th\u003e\n\u003ctd\u003e19\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions (LxWxH)\u003c\/th\u003e\n\u003ctd\u003e4.5 × 3.1 × 1 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"ROBODIUM","offers":[{"title":"Default Title","offer_id":62516385612147,"sku":"R1113","price":666.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/3620\/7475\/files\/1_ae1a1db7-0d37-49d8-a4da-841323b6e579.png?v=1770658544","url":"https:\/\/robodium.com\/products\/ai-thinker-vc-02-offline-speech-recognition-control-module-1","provider":"ROBODIUM","version":"1.0","type":"link"}
