Control Modes Serial (full function) and universal input (partial function). General output pins on the board can generate different signal types while recognizing the corresponding voice commands. Complete Kit Each package includes 1 Voice Recognition Module and 1 compatible component, providing the core components for training and implementing voice commands in your project. Parameters Voltage: 4.55.5V Current: 40 mA Digital interface: UART interface and 5V TTL level for GPIO Analog interface: 3.5 mm mono connector + pin interface Detection accuracy: 99% Features Supports up to 80 voices Multiple voices can be activated simultaneously The user needs to enroll/train the voice before it can be recognised Use scenarios Smart home automation: integrate the module to control lights, fans, or other devices with registered voice commands. DIY robotics and projects: add hands control to a small robot or robotic arm for simple commands such as move, stop, or action tasks. Prototyping and experimentation: build voiceactivated switches, alarms, or controllers for learning, testing, and development projects.
