Customer Questions & Answers

What are the key functions of the voice recognition board and how does it integrate with Arduino?

The board allows recognition of up to 15 custom voice commands that can be used to control devices via Arduino. It integrates via the UART interface (5V TTL), making it easy to connect to standard serial ports on most compatible Arduino boards.

What type of microphone is compatible, and what is included in the box when buying the board?

It supports mono microphones with a 3.5 mm connector, standard for desktop microphones. Usually the package includes only the board; cables and microphone are usually sold separately, but it is recommended to check the contents with the specific seller.

What are the power requirements and electrical limits of the board?

It must be powered between 4.5 V and 5.5 V DC, with a typical consumption of less than 40 mA. The data logic level is 5V TTL; exceeding the voltage range may damage the board.

What accuracy and reliability does command recognition have in noisy environments?

Voice recognition is optimised for moderately quiet environments. In noisy environments, accuracy may decrease significantly due to the limitations of the algorithm and hardware without DSP filtering; it is recommended to record commands in conditions similar to their final use for best results.

How many voice commands can this board recognise?

The board can recognise up to 15 different voice commands.

What voltage does the Arduino voice recognition board use?

It operates with a supply voltage between 4.5 and 5.5 volts.

What type of digital interface does this board use?

It uses a 5V TTL UART interface to communicate with Arduino.

Can I connect any microphone to this board?

The board has a 3.5 mm mono microphone connector, so a microphone compatible with this input should be used.

Is it compatible with all Arduino boards?

It is compatible with Arduino boards that support 5V TTL UART communication.
