Connecting Speakers
We have designed a speaker interface to connect at the output of the rest of emi circuits. It is a small circuit when you can find a trimmer to modify the volume and a couple of pin headers to interface with another circuits.
Schematics:
Important: There is a mistake in the pin headers labels in our boards. The input and output labels have been interchanged so you have to solder the speaker to the pin header labeled "IN".
