• An example screenshot image is very helpful
• Ensure that the associated footprints match the official footprint library
  • A new fitting footprint must be submitted if the library does not yet contain one.
  • The corresponding footprint is OLGA8 which is not in the library yet, but I have not drawn a footprint yet and I don't feel confident enough to do it myself. Edit: I made it
• If there are matching footprint PRs, provide link(s) as appropriate
