Schematics diagrams of the Harmonizer modules

The file consists of schematics circuit diagrams prepared in KiCAD version 6 for the individual printed circuit boards of the Harmonizer. The designs of the printed circuit boards are not made public as post-manufacture modifications have been made to them. The schematics reflect these changes to the physical boards, but updated designs of the PCBs have not been produced. The original printed circuit designs may be requested from the authors if required.
