Final design of Microphone PCB

The final PCB design can be seen in the tab sprint 3 -> Electronics -> Microphone PCB. The final design of the PCB is presented in the Slave Node Section.

Figure 1:PCB of the microphone circuit

However during testing there were difficulties trying to record and send the all of the samples, which lead to having a big loses in audio. A more detailed approach is found in sprint 5 -> Hardware -> Microphone PCB, where it is presented how an AUX cable was soldered onto the existing PCB. The AUX cables makes the operation of the microphone circuit easier, since any device recognizes it as normal microphone.
