Frequently Asked Questions

What is the operating voltage range for the HS-S57-L module?

The module is designed for dual-voltage operation, accepting a DC supply from 3.3V to 5V. This makes it directly compatible with most 3.3V logic microcontrollers (like ESP32) and 5V systems (like standard Arduino Uno) without requiring a level shifter.

How do I communicate with this speech recognition module?

Communication is via a standard UART serial interface using the TX (transmit) and RX (receive) pins on the PH2.0 connector. You simply connect these pins to the corresponding UART pins on your microcontroller (e.g., GPIO1/3 on ESP32, Digital 0/1 on Arduino) and use serial commands to send and receive data.

Does this module require any external microphone or speaker?

The HS-S57-L module requires an external microphone for audio input and likely an external amplifier/speaker for audio feedback, as these are not included on the board. You will need to connect a compatible microphone to the SU03T IC's input pins (consult the SU03T datasheet for pinout) for it to capture voice commands.

Can I train this module with custom voice commands?

The capability for custom command training depends on the firmware of the underlying SU03T chip. Some versions support a limited set of pre-defined commands, while others may allow training via a specific serial protocol. You would need to refer to the SU03T documentation or the vendor's software tools to configure custom keywords.
