LUASR01 Voice Recognition Module Offline Voice Control for Arduino Smart Home

LUASR01 Voice Recognition Module Offline Voice Control for Arduino Smart Home Description

Intelligent Speech Recognition Module LUASR01 Overview A compact speech recognition module designed for easy integration into electronics projects. LUASR01 provides multiple configurable IO ports, an onboard speaker output, and low standby power for battery or USBpowered systems. Key benefits Adds voice control and speech feedback to projects without complex hardware. Multiple configurable IOs and PWM support let you directly drive LEDs, relays, motors, and servos. Low standby current conserves power in battery applications. Wide input voltage range and builtin audio output reduce the need for extra components. Main features Model: LUASR01. IO ports: Eight IO ports labeled 101 to 108. Ports 101 to 106 support output functions and can operate in PWM mode when needed. Ports 107 and 108 are general IOs that can output and low levels, pulse signals, and servo signals. Speaker output: Supports an 8 ohm speaker with up to 3 W power. Power consumption: Standby current about 10 mA. Typical supply current 500 mA during operation. Power supply range: 3.6 to 5.8 V, standard use at 5 V. Operating temperature: 20 C to 80 C. Materials and appearance: PCB and plastic construction. Color as shown. Different production batches may vary slightly in appearance, color, or printed markings without affecting functionality. Technical specifications Model number: LUASR01 IO labels: 101, 102, 103, 104, 105, 106, 107, 108 IO capabilities: 101106 support output and PWM use; 107108 support and low output, pulse signals, and servo signals Speaker: 8 ohm, 3 W Standby current: 10 mA Supply voltage: 3.6 to 5.8 V (use 5 V recommended) Operating current: up to 500 mA typical during use Operating temperature: 20 C to 80 C Material: PCB and plastic Package contents 1 x Intelligent Speech Recognition Module LUASR01 1 x Pin header Notes Only the items listed above are included. Color and printed markings may vary between batches. Minor measurement error allowed: +/ 1 to 3 cm. Light reflection and display differences may slightly affect perceived color. Practical applications Voicecontrolled robotics: Use speech recognition to trigger motor actions, move servos, or change robot modes via the module outputs. Smart home prototypes: Implement voiceactivated lighting, relays, or status prompts with onboard audio feedback. Educational electronics and interactive toys: Add speech input and sound output to learning kits, DIY projects, and hobby builds without additional audio hardware. Integration tips Use a stable 5 V supply capable of supplying at least 500 mA for reliable operation. Map IO ports 101 to 106 for PWMdriven devices such as motor controllers or dimmable LEDs, and use 107 and 108 for general purpose outputs or servo signals. Mount on a stable PCB or enclosure to protect the module and speaker connection. This module is suitable for makers, prototypers, and developers who need a straightforward speech recognition and audio output solution with multiple configurable outputs and low standby power.
