Chip:GPD2846A Chip Footprint:SOP16 PCB Size:34.23MM*22.33MM*1MM with 2W Mixed mono With Power supply ,it can play Automaticly With LED indicator Supports MP3 format playback Supports USB audio mode Supports 3 types FM radio chip : RDA5807, BK1080 and RTC6207E. Does not support infrared remote control. Does not support USB device mode Description: TF card MP3 decoder board decoder module 3.7-5V power supply with 2W mixed mono, with memory playback, volume memory TF card MP3 decoder board, without TF card, supports playback of MP3 music files, currently tested 16G TF card support, the larger one has not been tested yet 3.7 Lithium battery or USB 5V can be powered, The 3 groups of white boxes in the upper right corner of the board are 3 groups of touch buttons, the middle group is the play pause key, the up and down 2 groups are short presses for the up and down music keys, and the up and down 2 groups are long press for the volume +- adjustment. With 2W mono power amplifier, the maximum output of the power amplifier is 3W when powered by 5V (it is recommended to match the small speaker on the 4 ohm 3W card small speaker, the sound quality is good, the sound is loud, if the volume is not enough, please change directly to 4 ohm 5W Speaker, the sound is so loud that it scares you. After changing to a 4 ohm 5 watt speaker, pay attention to the heat dissipation of the power amplifier chip, it is best to add a heat sink) Some customers reported that when the amplifier is playing music, it will generate heat. It is normal for the amplifier chip or the amplifier tube to heat up. As long as the amplifier is not turned on to a high volume, the output terminal of the speaker (resistance value 0 ohm) will not burn the amplifier. The chip can be used with confidence. Some customers need to go back and use this board as the pre-amplifier of the power amplifier. You don’t need the power amplifier of this board. Go back and connect the power amplifier yourself. You can modify as follows, remove the power amplifier chip (8-pin chip) of the board, and then remove it from the main control Pin 4 and Pin 6 (these two pins are the left and right channel output of the main control chip), connect a 104 (or 224) capacitor in series to the input end of the power amplifier (the capacitor acts as an isolation to prevent the same power supply When burning the front-level main control chip or the later power amplifier tube), the remaining wire is connected from the negative terminal to the common terminal of the power amplifier input Auto play after power-on
