:
Most of the I2S decoding boards on Xbao are based on the PCM51XX series, with a price of more than 15, and the wiring is troublesome, and xmt needs to be set to a high level. The TM8211 decoding IC is less than 1 yuan, and the component cost of this decoding board is about 3-4 yuan. It is a dual-channel decoding board suitable for the ESP32 series development board, and the dual-channel FM8002D power amplifier circuit is integrated on the board. Through the switch key, two 1-2W small speakers can be directly driven. Of course, you can also use the audio cable directly without soldering the power amplifier circuit, connect it to the 3.5mm audio interface designed on the board, and play it with the speaker.
