【Speech recognition positioning】PCB design and proofing of microphone array [Copy link]

 

The PCB design of the microphone array is completed, and I am ready to make the board. The previous post shared the schematic diagram. I wanted to edit it directly from that post, but it is no longer editable, so I opened another post. One reason is that I am busy, and the other is that I tried to use KiCad to draw the PCB. The schematic diagram is easy to use, but it took a little time to draw the PCB. I feel that KiCad is still very easy to use after drawing it, and I don’t have to worry about piracy. I plan to use KiCad in the future.

But KiCad doesn't know how to draw arcs when routing, so the lines on the board don't look very good. Please forgive me. Here is the PCB diagram:

Awesome, KiCad

I have used this software several times and it is not as difficult to use as I imagined. It can meet most of the basic functions. I will use KiCAD when I do my own projects in the future . FreeCAD for drawing three-dimensional images is not easy to use.
