Product Instructions


The module has three power supply options: battery, USB, and DC power. After powering on, the phone searches for the Bluetooth name HW-407, and once connected to Bluetooth, music can be played. There is a blue LED indicator light on the module, which has the following functions:

Product Note


1. Signal interference: Bluetooth antennas are extremely susceptible to high-frequency or strong electromagnetic signal interference, so they should be placed as far away as possible from transmitting wireless devices. And the board should not be in close proximity to metal objects, maintaining a certain distance.


2. If there is a current sound when connecting to the power amplifier board, it is caused by ground wire interference. It is recommended that the output end of the Bluetooth module should not be plugged in, and must be soldered, especially for the ground wire. The wire should not be too long, the shorter the better, and it should be thicker as much as possible. The issue of the audio ground being connected to the grounding point of the amplifier board requires it to be connected to the ground at the audio input end of the amplifier. This grounding point can be welded at different positions to achieve the lowest current sound. Suggest separate power supply for Bluetooth and amplifier board, isolating Bluetooth ground and amplifier ground.


3. Due to the bare board design of this product, try not to touch the components on the board with your hands, as it may cause static electricity to kill the chip and burn it out.


Warning: The charging interface of this product is limited to current charging mode and does not come with charging management! For the safety of your life and property, please make sure to use lithium batteries with protective plates produced by legitimate manufacturers. If any losses are caused due to improper use, our company will not be held responsible.
