## Description

Audio playback module for electronic and industrial projects, offers MP3/WAV playback with flexible control via UART, I/O or One-line, includes 5W class D amplifier for 4 ohm 3-5W speakers, has integrated 8MB Flash memory without SD card and allows file updating via Micro USB, includes 3.5mm audio jack output for quick connection.
The intelligent voice playback module, DY-SV8F, developed to integrate functions such as I/O subsection triggering, UART serial port control and ONE-line single serial bus control. It includes a built-in Class D 5W amplifier and can directly drive 4ohm speakers with 3-5W. It supports MP3 and WAV formats and comes with 64Bbit (8Mbyte) Flash memory, without SD CARD support .
The module allows updating audio files via USB and includes a 3.5mm audio interface, Micro USB download interface and a button module.
The speaker can be glued directly to the wood or it can be connected, if an XH2.54 female connector has been mounted beforehand, directly through the plug.

Instructions:
1. Connect the 4ohm 3-5W speaker to the module.
2. Connect the module to the 5V DC power supply.
3. Load the desired audio files using the Micro USB cable.
4. Use the UART or I/O port to control playback functions.
The INDEPENDENT modes only work if the name of the mp3 files is as in the table below (00001.mp3, 00002.mp3, samd).
Power through the GND next to the power supply, NOT the GND related to the buttons. The GND of the buttons does not have routes designed to cope with the 5W power to the amplifier.
The buttons have a default state of 1 (High). By putting them to ground (GND), the state of the button goes to 0 (Low). So, in the tables below, 0 corresponds to connecting the button to GND.
