Audio Filter Board


These will be back in stock soon, just waiting for the new revision to arrive (hopefully by the end of May).

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 output pin holes match the input pins of the 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)

150 Ohm SMD Resistors on eBay or Amazon
270 Ohm SMD Resistors on eBay or Amazon
33nF SMD Capacitor on eBay or Amazon
10uF SMD Capacitor on eBay or Amazon
