Help wiring pi Zero to “teensy”

[Flash4824]

So I’ve wanted to build a pi boy for years now and I finally got around to it. I ordered parts years ago but now I have no idea what or how to wire up my “teensy” (Don’t want to waste parts) I ordered this a long time ago and idk if I can use it or if I need to order something else? Does anyone have any ideas that can help me use this item?
