Hey, I made an autorouter plugin for KiCad. It also made the most complex PCB you'll ever see:

@violenceworks wth was the backplane with connectors that big?

@penguin42

It's a horrible hack of Molex SlimStack connectors. They don't make a 1000-pin version, but they do make a 50-pin version. So I put two females on either side of a board and spaced the males out on the backplane.

It's the highest density edge connector I can come up with, at least until I break into the Samtec warehouse.
