DigiKey's KiCad library is really broken 4 hours ago
tl;dr: Don't use DigiKey's KiCad library. Obviously, you shouldn't trust random libraries on the Internet. Heck, you shouldn't trust the actual KiCad libraries most of the time. I'm still annoyed about this because I've got a pack of useless PCBs. DigiKey, for whatever reasons, has been trying to…
