Control Modes Serial (full function) and universal input (partial function). General output pins on the board can generate different types of outputs while recognizing the corresponding voice commands. Power, Interfaces, and Performance Power supply: 4.5–5.5 V; Current draw: 40 mA. Digital interface: UART interface and 5 V TTL level for GPIO. Analog interface: 3.5 mm mono connector plus pin interface. Detection accuracy: 99%. Complete Kit Each package includes 1 Voice Recognition Module and 1 compatible accessory, providing the core components for training and implementing voice commands in your project. Compact Design and Integration Small form factor for easy integration into compact DIY projects such as robotics, home devices, and interactive toys. Use scenarios Robotics: implement voicetriggered actions to control movement, enable/disable subsystems, or start programmed routines without physical controls. Home automation: connect to a microcontroller to execute commands like turning lights on/off, adjusting devices, or activating scenes through spoken phrases. Interactive toys and educational kits: create responsive, voicecontrolled features that illustrate natural interaction concepts and enhance handson learning.
