Hi, I'm in the process of making a mini portable microphone amplifier on a single layer PCB.
I'd like your opinion about my work so far.
My goal is a small PCB with the circuit powered by a single 3.7V LiOn rechargeable battery.
My greatest fear is noise and interference. I did a test run using wire-wrap and a 9V battery, and it turned out to be OK.
However I fear the results once it's on the PCB... any recommendations (component placement, track widths etc)?
It's the first board I'm making all by myself
Thanks
