From the project

Note: use the BOM included in this repository. Some of the components have been relabelled in this revision so the BOM on SinPhi's website is no longer current.

1) Updated the footprints and symbols to ones included in KiCAD 5.1.5, or otherwise included the auxillary libraries in the repository.

2) Made the 4QX output no longer inverted and added a jumper pin on the back that allows you to switch between (non-inverted) summing and 4QX modes.
