Pin Definition

• Power Supply: Connect 5V and GND appropriately.
• TXD/IO0, RXD/IO1: For UART control or IO triggering.
• IO2 - IO7: Additional IO triggers.
• BUSY: Indicates playback status.

IO Characteristics

• Input Levels: Low (0-0.8V), High (2.7-3.3V).
• Output Levels: Low (0-0.33V), High (2.7-3.3V).

Dip Switch Mode Configuration

• CON1, CON2, CON3: Configure low/high level for different control modes.

Module Interface and Functions

• The module supports various operating modes, including independent IO control, combined IO control, UART serial port mode, and standard MP3 mode.
• Each mode can be configured for specific playback behaviors like track selection, volume control, and playback mode (e.g., loop, random).
