Description

H07R3x is an audio amplifier and speaker module based on ST TS4990 1.2W audio amplifier and STM32F0 MCU. This module features an on-board 8-ohm rectangular CUI speaker and a headphone output jack. Use this module to play sounds and tunes stored in the MCU embedded Flash or streamed from an external hardware/another module via array ports.

This project is basically a wave file player. you can use CLI command to play your favorite wave file.
