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 supports 150 local offline commands and a lightweight RTOS system, making it easy to customize with a variety of peripheral interfaces.<\/p>\n<h2>Features<\/h2>\n<ul>\n<li>All GPIOs can be set up as external interrupt inputs and wake-up sources<\/li>\n<li>One full-duplex UART with a maximum speed of 3Mbps<\/li>\n<li>Supports I2C, DAC, PWM, and multiple interfaces<\/li>\n<li>Includes 242KB of high-speed SRAM<\/li>\n<li>Equipped with 2MB FLASH memory<\/li>\n<li>Dual-channel DAC output support<\/li>\n<li>32-bit RISC core running at 240MHz\n<\/li>\n<li>Supports DSP instruction set and FPU for floating-point operations<\/li>\n<\/ul>\n<h2>Package Includes<\/h2>\n<p>1 x Ai-Thinker VC-02 Offline Speech Recognition Control Module<\/p>\n<h2>Specifications<\/h2>\n<table border=\"1\">\n<tbody>\n<tr>\n<th>Item Type<\/th>\n<td>AI and Voice Module<\/td>\n<\/tr>\n<tr>\n<th>Model<\/th>\n<td>Ai-Thinker VC-02-Kit<\/td>\n<\/tr>\n<tr>\n<th>Supply Voltage (V)<\/th>\n<td>5<\/td>\n<\/tr>\n<tr>\n<th>Current (mA)<\/th>\n<td>500<\/td>\n<\/tr>\n<tr>\n<th>Weight (g)<\/th>\n<td>19<\/td>\n<\/tr>\n<tr>\n<th>Dimensions (LxWxH)<\/th>\n<td>4.5 \u00d7 3.1 \u00d7 1 cm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Ai-Thinker VC-02 Offline Speech Recognition Control Module The VC-02-Kit is a development board for the VC-02 module, sharing the same design as the VC-01-Kit.
