Audio Filter Board


This board is detailed here.  This is a simple passive audio filter to get better quality audio from the PWM. It is meant to be used in combination with an audio amplifier. The amplifier isn’t required, but output volume will be very low unless you’re just using headphones.The output pin holes match the input pins of a standard PAM8403 audio amplifier.

This board is not specific to the PSPi. It will work with any project.

The following components are used on this board (if you prefer to build your own)
