Audio Playback - MICRO Module

High-Quality Audio in a Compact Module

The Audio Playback – Micro Module is designed to play audio files in high-quality compressed format. With built-in storage for approximately 40 seconds of audio, this module is ideal for applications requiring small voice prompts or messages.

You can store up to 3 different voice messages, each triggered through dedicated inputs – making it perfect for simple, reliable audio feedback in your projects.

Key Features

Built-In Power Amplifier

The module includes an on-board power amplifier that can directly drive a speaker. The audio output is loud enough for most applications – no external power amplifier required.

Wide Power Supply Range

Powered by a 6V – 12V DC power supply, the module features:

• On-board 5V regulator

• Reverse supply protection diode for safety

Easy Integration

• Compact form factor

• Simple trigger inputs for each message

• Ideal for embedded and IoT systems

Options (Configurable During Programming)

The following configurations are available when programming the module:

• Up to 3 voice messages – Total storage capacity of approximately 40 seconds

• Trigger input type – Choose between active-high or active-low (default: active-low pulse)

• Loop mode – Messages can be configured to play in a continuous loop after power-on (instead of pulse trigger)

• Interrupt behavior – Configure whether a new pulse:

• Interrupts the current audio to play the new message

• Or ignores new triggers while playing (interrupt disabled)

• Volume control – Adjustable in 30 steps during programming

Programming & Voice Customization

⚠️ Important Note:

This module requires a special device and software to convert and program audio files into the chip.

End-users cannot change the voice content themselves.

Customers must send their MP3 audio files to us for conversion and programming.

Applications

The Audio Playback – Micro Module is suitable for a wide range of applications, including:

• Voice prompts in consumer electronics

• Interactive toys and educational devices

• Public announcement systems

• IoT devices with audio feedback

• Automotive systems (e.g., GPS voice guidance)
