Overview:

• Chip:GPD2846A

• Support MP3 playback formats

• working voltage of 3.7 to 5-V

• Onboard 2W mono audio amplifier

• TF card slot for a micro-SD memory card 

Description:

This TF card MP3 decoder board utilises the GPD2856A MP3 decoder IC and has an onboard 2W mono audio amplifier IC (8002). This module is the updated version of the earlier GPD2846A TF card MP3 decoder board, and in this latest version, there is a TF card slot for a micro-SD memory card and an LED power indicator. The board requires only a power supply, direct speaker connection, and switches.  

Features:

• Support MP3 playback formats

• Playable T card / SD card, U disk, FM, and external audio sources (LineIn),inserted after the first broadcast, but also by Mode key switch.

• Automatically detects the headset is plugged in, and so by the IO port (Mute)

• Switch the external power amplifier directly, without external transistor.

• Support the volume size, the number of songs stored onT card / SD card, Udisk, users can save EEPROM

• It can automatically detect and decide whether an external EEPROM inEEPROM or T card / SD card, U disk, save the settings.

• In an AD-key port to achieve a variety of button combinations.There are two groups AD-key keyboard to choose from.

• FM radio chip supports 3: RDA5807, BK1080 and RTC6207E.

• It does not support infrared remote control,USB device mode nor USB audio mode.
