Product Description:
1. Power supply: You can directly use Type-C 5V for direct power supply, or you can additionally access 5V power supply or 3.7V lithium battery (as shown in the picture below). Note that the 5V and 3.7V power supply interface is different, 5V is connected to 5V and GND, 3.7V lithium battery is connected to VBAT and GND.
2. Maximum working current 5V2A, it is recommended to use 5V2A regulated power supply for better sound quality.
3. Support USB sound card, no driver (plug and play). Connect the module to the computer with the USB cable, the computer can play music through the module amplifier output
4. Audio output: output left and right channel stereo audio signal, can be connected to two 2-8Ω, 3-5W speakers, pushing the storage with 4Ω 5W speakers.
5. This product already comes with a double 5W amplifier circuit, do not connect another amplifier to use! The output of the two amplifiers must not be connected in parallel or connected together with the negative pole, otherwise the amplifier chip will be damaged.

Caution:
Signal interference: Bluetooth antenna is extremely susceptible to high frequency or strong electromagnetic signal interference, try to place away from the place of sending wireless and other equipment. And the board can not be close to metal objects, keep a certain distance.
If you connect the amplifier board with current sound, caused by the cause of ground interference caused by the proposed Bluetooth module output do not use plug lines, need to weld the line, especially the ground line to be soldered, and the line can not be too long, the shorter the better, as thick as possible. Audio ground in the amplifier board ground problem, need to be connected to the amplifier audio input end of the ground, this ground can try to weld in a different location to achieve the lowest current sound. It is recommended that the Bluetooth and amplifier boards are powered separately to isolate the Bluetooth ground from the amplifier ground.
As this product is designed as a bare board, try not to touch the components on the board with your hands, it will easily lead to electrostatic death of the chip resulting in burnout.
