DY-HV8F is an intelligent voice module that can be used to play sound/music. Just upload the sounds that are be to played through USB, connect a suitable speaker to this module and you can start playing music/sound/voice files. All required operations can be performed over UART - select file, start / stop playback, increase / decrease volument, etc. Internal storage eliminated the need to add an external SD Card.
This module makes it easy to add sound playback functionality to microcontroller like - Arduino, ESP32, Raspberry Pi etc. The sound files can also be played independently, without the need for a microcontroller. The sould files can be played by passing digital IO signals to the specific pins (check datasheet for more info). Switches can be used to control the sound playback.
This module is great for playing audio files in voice assitants, GUI menus, greeting and alert messages, greeting cards, welcome messages, etc.
It allows I/O triggering, UART serial control and ONE_line single bus serial port control. Onboard 20W Class D amplifier circuit and can directly drive 4ohm 20W or 8ohm 10W speakers.
Support MP3, WAV decoding format.
Note: We have the similar boards with support for reading external SD Cards. We also similar modules in different output power ratings.
