This is the PCB for the Mimir's Well pedal.
I recommend getting a partial kit instead, if you want to build this pedal.
But if you're comfortable burning EEPROMs, programming microcontrollers, and doing SMD soldering... this is for you! Docs here: https://github.com/mstratman/fv1-pedal-platform
You can also get your EEPROM sets here.
