Description

The SU-03T1 module utilizes an integrated AI processor for real-time, offline voice command recognition. It processes audio input from its onboard microphone, converting specific phonetic patterns into actionable digital commands via a serial UART interface. This design eliminates cloud dependency, ensuring low-latency control for embedded systems.

Engineered for stable operation within a 3.3V to 5V DC range, the module is compatible with common 3.3V and 5V logic families. Its 115200 baud serial communication protocol allows for straightforward wiring and command parsing with development platforms like Arduino, ESP32, and STM32. The module’s structure includes standard 2.0mm mounting holes for secure installation in end-user devices.

Key Features

  • Standalone Offline Operation: Processes voice commands locally without Wi-Fi or external servers, ensuring privacy and instant response.
  • Custom Command Training: Supports rapid definition and training of custom wake words and action phrases through the manufacturer's web platform.
  • Developer-Friendly SDK: Provides open-source libraries and examples for integrating custom logic and expanding functionality.
  • Robust Audio Front-End: Features a high-sensitivity microphone and audio conditioning circuitry for reliable performance in varied acoustic environments.
  • Broad Compatibility: Interfaces seamlessly with common serial adapters (e.g., CH340) and is pin-compatible with related voice module series for design flexibility.
  • Optimized Performance-to-Cost Ratio: Delivers advanced voice recognition capabilities in a compact, ready-to-integrate module.

Applications

  • Smart home appliance control (lights, fans, switches) via voice commands.
  • Interactive toy and educational robot voice interface integration.
  • Industrial human-machine interface (HMI) for hands-free machine control.
  • Voice-activated automation in IoT projects and DIY maker builds.
  • Accessibility devices providing voice-controlled operation for users with limited mobility.

Frequently Asked Questions

What is the operating voltage range for the SU-03T1 module?

The SU-03T1 module operates from 3.3V to 5V DC. It is crucial to stay within this range; applying voltages outside it may damage the internal AI processor and audio circuitry. For stable performance, ensure your power supply can deliver clean, regulated voltage within these limits.

How do I communicate with and program the SU-03T1 module?

Communication is via a standard UART serial interface at 115200 baud. You connect the module's TX and RX pins to your microcontroller's corresponding RX and TX pins. To program custom voice commands, you use the manufacturer's web-based Smart Era platform to generate and flash the firmware, which typically does not require traditional coding.

Can I use this module without an internet connection?

Yes, the SU-03T1 is designed specifically for offline operation. All voice processing and command recognition occur locally on the module's chip. This makes it ideal for applications where internet connectivity is unreliable, unavailable, or where data privacy and low-latency response are critical requirements.

What is included in the package?

The package includes one SU-03T1 intelligent voice recognition module. It is the core module only and does not include peripheral items like a microphone (which is integrated), speaker, serial adapter, or cables. You will need to provide these separately based on your project requirements.
