Frequently Asked Questions

What is the operating voltage and communication interface for this voice recognition module?

The module operates at 3.3V DC and communicates via a standard UART serial interface. The default baud rate is 9600 bps, and it outputs recognized command IDs as serial data packets to the host microcontroller.

How many voice commands can the ACEBOTT V2.0 module recognize, and can they be customized?

This module is pre-trained to recognize up to 80 predefined voice commands. The command set is fixed in the factory firmware; user customization or training of new commands is not supported on this version.

Is this module compatible with 5V Arduino boards like the Uno?

The module itself requires a 3.3V power supply and uses 3.3V logic levels on its UART pins. To interface with a 5V Arduino, you must use a logic level converter on the TX/RX lines to avoid damaging the module's input circuitry.

What is the typical recognition range and environmental performance?

Equipped with a -38dB sensitivity microphone and a ≥60 dB SNR, the module is designed for clear command capture in typical indoor settings at conversational distances (1-3 meters). Performance may degrade in very noisy environments.
