“I recently made an interesting wireless speaker project that was a finalist in the PCB competition.
You can check this post by clicking here and the video as I created by clicking here. I used PCB for this, which I made myself and as I announced, I also made it on a professional board. This is my first purchased PCB and I am very satisfied with it. In the previous post, I described the project stages from idea to prototype, and in this project, I will focus on finalizing the project.
It cost me around $ 15, here is a set of elements:
RDA5807
ATMEGA328P-AU
128x32 OLED I2C
SMD ENCODER
SMD TACT SWITCH
PCB
5V Battery”
