DIY Bluetooth Mini Speaker Conversion

If you are interested in making a DIY Bluetooth mini speaker, you can take a look at this article.

If you happen to have two Bluetooth 5.0 modules and a portable speaker, you may suddenly come up with the idea of modifying the speaker into a Bluetooth speaker. After preparing all the required materials, you can start the project. At this point, you notice that the Bluetooth module has + and - input soldering points, which should be connected to the power supply of the Micro input port. Therefore, you cut a Mini cable and solder it onto the Bluetooth module, completing the power connection with a single power cable. In fact, the charging module is also available, but using an external power supply provides unlimited power, so you do not need to worry about repeated charging.

You can measure the power consumption of the entire speaker, and surprisingly, it is only around 0.1A, which is quite unexpected. The project is complete.
