Mini Speaker Bluetooth Portatile Fai-Da-Te
Print Profile(1)
Description
Print your custom case and bring it to life with this fantastic DIY electronics project! I created this compact yet powerful setup to achieve high, clear volume from a very small space
Unlike classic basic circuits, this project uses a Step-Up module (MT3608) to boost the 3.7V LiitoKala battery to a constant 5.0V. This ensures that the DW-CT14+ Bluetooth board operates at full power (3W + 3W) without audio distortion even when the battery starts to drain
If you plan to print your own enclosure (shell) for this circuit diagram, you will find my Complete PDF Manual with the wiring diagram and the correct component calibration order among the downloadable files
