An audio playback module with inbuilt memory is a compact device designed to play audio files stored in its internal memory. These modules are commonly used in embedded systems, IoT devices, toys, and other applications where space and power efficiency are critical. This Audio Playback - Mini module is used to play audio files in high quality MP3 format. The module has inbuilt small storage to save the audio files. The approximate audio length that can be stored in to the module is 40 seconds. The module is highly useful in many applications where a small voice prompt or message needs to played. There is an option to save up to 4 different voice messages and the same can be activated through induvidual inputs for each message.
The module has in-built power amplifier which can drive a speaker. The audio will be loud enough and there is no need for external power amplifier.
This module has additional DAC output also which can be connected to external amplifier circuit. Either DAC output or inbuilt amplifier can be choosen with the configuration. Both will not work simultaneously.
The module can be powered by 6V - 12V DC power supply. There is an on-board 5V regulator in the module. Reverse supply protection diode is also populated in the modue.
Options:
Following configurations are available when programming the module.
Maximum 4 voice messages can be stored with total capacity of approximately 40 seconds.
Voice messages can be triggered with either active-high or active-low input. Default will be active-low pulse.
Messages can be configured to play in loop mode after power on instead of pulse trigger.
Giving a pulse when playing audio can be interrupted to play the new audio or else interrupting while playing can be disabled.
Volume can be adjusted while programming in 30 steps.
Applications:
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).
This product can be customized as per need.
