This is a smaller version of the Pythagoras from PedalPCB.com for creating Reverb, Delay, Flange or Chorus effects. The intent is to make it as small as possible for embedding into a combo-pedal format. The control POT footprint is for Alpha 9mm vertical POTs but can also use vertical trimmer pots for "set it and forget it" embedding. The mouser links in the BOM are for the trimmer pots, NOT the alpha 9mm. The eeprom and program select jumpers are on the bottom side of the board for easy access if using alpha pots.

Here's an interactive BOM for DIY. https://paulamps.com/boms/Spin%20FV1.html

I strongly suggest mounting the following resistors on the bottom side for easy access to tweak: R10, R11, R12, R16, R20.

These might need tweaked for signal level to and from the FV1 and the clipping LED brightness.

Tweaks are described in the BOM file.
