i'm building my digital stethoscope prototype and I'm wondering which part i need to build to be able to get the same design as per " Digital Stethoscope Implementation on the TMS320C5515 DSP Medical Development Kit (MDK" so when I click in the reference design example of the -signal protection input- i find 2 references design in the far right of the page. My question I need to build both of these references or I choose one? I hope my question is clear.
my second question: can we order the PCB board with the same design or we have to do it our self or send to PCB producer to build it.
This is just my first steps and I will have more question later LOL.
Thank you a lot for helping
