Audi is still picking up remote mic and internal mic. Ill try to open the camera and remove the internal mic, and solder a 1000 ohm resistor across the pads
After making hundreds of boards with PCB Express…. we grew out of them. They offer a very easy to use interface, walled garden approach. expensive boards. Something like 5 x the industry average.
I finally found EasyEDA. It is simple enough for my pea brain to operate. Lots of libraries built in. 3D view. Direct to JLCPCB to fab boards.
